From the two YouTube videos, I learned that cellular respiration is the process that happens inside our cells to produce energy. The food that we eat, especially glucose, is broken down to make ATP, which is the main energy source that our body uses. From the Amoeba Sisters video, I learned that cellular respiration has three main stages - glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis happens in the cytoplasm and breaks down glucose into smaller parts. The Krebs cycle and the electron transport chain happen in the mitochondria, which is called the "powerhouse of the cell."

From the Crash Course video, I learned that even though cells don't really "breathe," they still need oxygen to get energy. Oxygen helps in breaking down the glucose completely to release more ATP. The video also showed that when we don't have oxygen, cells can still make energy through fermentation, but it gives less energy.

Something interesting I saw:

What I found interesting in the Amoeba Sisters video was how they used cute cartoons and simple animations to explain the process. It made the lesson fun and easier to understand. I liked how they explained each stage with visuals that showed what happens inside the cell.

In the Crash Course video, I found it interesting how the speaker talked very lively and explained how cellular respiration is connected to real life, like how our bodies use energy from food to move and survive. The visuals and examples made me imagine how small processes inside our cells are actually very important for life.

I learned that the Cellular Respiration has two types. The Aerobic Respiration uses oxygen and produces alot of atp, while the Anaerobic Respiration happens even without oxygen but produces less atp. An example for Anaerobic Respiration is fermentation.

Also, lastly I've observed that there are 3 Main Stages of Cellular respiration, first is the Glycolysis which occurs in the cytoplasm, it only produces 2 ATP and it does not need oxygen, so it happens in both aerobic and anaerobic respiration. For the second one which is Krebs Cycle occurs inside the mitochondria which is called the mitochondrial matrix, it produces a small amount of ATP, only 2 amount, and this stage needs oxygen inorder to release carbon dioxide as a waste product. Third is the Electron Transport Chain, this one is located in the inner membrane of the mitochondria, it uses high energy electrons to create a flow of energy that makes ATP. In this part, most ATP is made. Oxygen is stated to be the final electron acceptor, and without oxygen, this stage cannot happen. This is the reason why oxygen is essential for aerobic respiration.

GENBIO

I learnt that Cellular Respiration is a process in which glucose is converted into adenosine triphosphate. This provides energy for cell movement, growth, repair, and equilibrium. There is a general equation for cellular respiration, which states that the combined glucose and oxygen break down into carbon dioxide, water, and ATP energy. The majority of cellular respiration occurs in the mitochondria, with the first part occurring in the cytoplasm.

I discovered that cellular respiration has two forms. Aerobic respiration needs oxygen to produce a lot of atp, whereas anaerobic respiration occurs even without oxygen but produces less atp. Fermentation is an example of anaerobic respiration.

Finally, I've discovered that there are three main stages of cellular respiration. The first is glycolysis, which occurs in the cytoplasm and produces only 2 ATP and requires no oxygen, therefore it occurs in both aerobic and anaerobic respiration. The second one, the Krebs Cycle, takes place inside the mitochondria, which is known as the mitochondrial matrix. It creates a little quantity of ATP, only two, and this stage requires oxygen to release carbon dioxide as waste. The third is the Electron Transport Chain, which is located in the mitochondria's inner membrane and employs high-energy electrons to generate a flow of energy that produces ATP. The majority of ATP is produced during this process. The ultimate electron acceptor is believed to be oxygen, and this stage cannot occur without it. This explains why oxygen is necessary for aerobic respiration.

It takes place primarily in the mitochondria, known as the powerhouse of the cell.

• ATP (adenosine triphosphate) is the cell’s main energy currency, powering most biological processes.

Three main stages of cellular respiration:

• Glycolysis – Occurs in the cytoplasm; converts glucose into pyruvate, producing a small amount of ATP and NADH.

• Krebs Cycle (Citric Acid Cycle) – Takes place in the mitochondrial matrix; releases CO2 and produces ATP, NADH, and FADH2.

• Electron Transport Chain (Oxidative Phosphorylation) – Happens in the inner mitochondrial membrane; uses NADH, FADH2, and oxygen to produce most of the ATP.

  • Oxygen acts as the final electron acceptor, forming water.

• ATP synthase generates ATP using a proton gradient across the mitochondrial membrane.

• The process is highly efficient, with one cell producing up to 10 million ATP molecules per second.

• Aerobic respiration requires oxygen, while anaerobic respiration and fermentation occur without oxygen.

• Fermentation produces less ATP but allows energy production in oxygen-deprived conditions.

• Cellular respiration releases energy in a controlled, prevents damage to the cell.

• ATP functions like a rechargeable battery, constantly being broken down and reformed to meet energy needs.

Amoeba Sisters - I learned how cells make ATP which is their energy, it also shows how cells convert food into energy that will they use. I also learned why and how important ATP is in everything we do.

Crash Course - I learned that mitochondria are like tiny power plants, making ATP to fuel everything we do from moving to thinking. The video also explains how rhe process works and is it essential in our life.

Isn't it interesting to learn that all chemical reactions in our body go through specific processes to function properly and produce the necessary substances to sustain life? Chemical reactions such as cellular respiration, protein synthesis, and digestion all follow detailed processes to work efficiently. For example, cellular respiration has three stages; glycolysis, the krebs cycle, and the electron transport chain, which have their own functions that must be performed to properly carry out the process to produce ATP.

next is the krebs cycle, which occurs in the mitochondria. it breaks down pyruvate into carbon dioxide, makes 2 more atp, and produces NADH and FADH₂ for the next stage. this step needs oxygen and releases carbon dioxide as waste.

the last stage is the electron transport chain (etc), also in the mitochondria. it makes most of the energy (around 32–34 atp). oxygen is very important here because it helps form water as a byproduct, and without it, this stage can’t happen.

Cellular respiration has several stages: Glycolysis, the Intermediate Step, the Krebs Cycle, and the Electron Transport Chain (ETC).

The Electron Transport Chain takes place in the inner mitochondrial membrane and produces the most ATP

Glycolysis happens in the cytoplasm and breaks one glucose molecule into two pyruvate molecules, producing a small amount of ATP and NADH.

- Cellular Respiration : Amoeba Sisters and Do Cells Breathe? : Crash Course Biology #27

After watching both videos, I learned that cellular respiration is how our cells turn food into energy. It’s not the same as breathing with lungs, but cells breathe in their own way.they use oxygen and release carbon dioxide to make ATP which is the energy our body needs to function. The process in the Amoeba Sisters video was explained step by step. It starts with glycolysis in the cytoplasm, where glucose is broken down into pyruvate and a bit of ATP. Then in the Krebs Cycle inside the mitochondria, more energy carriers like NADH and FADHv2 are made while carbon dioxide is released. Finally, in the Electron Transport Chain, oxygen is used to produce a large amount of ATP and water. The video also mentioned fermentation which happens when there’s no oxygen but it makes less ATP.

The Crash Course Biology video explained it in a more conceptual or theoretical way.it said that cells don’t literally breathe but still need oxygen for the chemical reactions that produce energy. When we inhale, oxygen goes to our cells, and then when we exhale, the carbon dioxide we release is actually a byproduct of cellular respiration.

So from both videos I realized that ATP is the cell’s main source of energy and without it, our bodies wouldn’t be able to move or survive. I also liked how the process was compared to a factory, wherein glucose is the fuel, oxygen keeps the machines running,and ATP is the product.

The 2nd video, it explalins that cells use oxygen to make energy even if they don’t really breathe, it shows how cells break down glucose to produce atp and it also talks about what happens when there’s no oxygen, like in fermentation and they also compares cellular respiration to human breathingfor us to understand it better. I learned that all cells need energy to live and do their jobs

‎I also learned that it has sa several stages the Glycolysis, the Intermediate Step, the Krebs Cycle, and the Electron Transport Chain (ETC) by this i'm able to know that glycolysis happens in the cytoplasm and breaks one glucose molecule into two pyruvate molecules, producing a small amount of ATP.

‎While NADH and Electron Transport Chain takes place in the inner mitochondrial membrane and produces the most ATP.

Now I know the importance of cellular respiration in my body, so thank you for this lesson. I learned about the process in my body, so I will value myself even more."

What I learned from watching the video is that cellular respiration is important for cells because this is where they make ATP using glucose, which is beneficial and very helpful for the cells. Glycolysis helps by breaking glucose into smaller parts, and it encouraged me to keep watching because all the functions of each part were clearly explained.

Here's my key points:

- Glycolysis (in the cytoplasm, no oxygen needed) breaks glucose into pyruvate, producing 2 ATP and 2 NADH.

- Krebs Cycle (in the mitochondrial matrix, requires oxygen) converts pyruvate to acetyl CoA, releasing CO2 and generating 2 ATP, 6 NADH, and 2 FADH2.

- Electron Transport Chain and Chemiosmosis (in the inner mitochondrial membrane, requires oxygen) use electrons from NADH and FADH2 to create a proton gradient that drives ATP synthase, producing most ATP, with oxygen as the final electron acceptor forming water

.

From CrashCourse, I learned that mitochondria create ATP and keeps us functioning. The video discussed each step of cellular respiration and how oxygen must be presented to finish the process. I was able to appreciate how incredible it is that this small part of a cell is able to create the energy needed for everything we do, including breathing and thinking.

Cellular respiration is the process by which cells break down glucose and other food molecules to release chemical energy. The primary goal is to produce Adenosine Triphosphate or ATP, which serves as the energy change for the cell, powering all life activities.

The process is by this equation: Glucose+Oxygen→Carbon Dioxide+Water+Energy (ATP).

Aerobic vs. Anaerobic: The most efficient type is Aerobic Respiration, which requires oxygen.

ATP: The readily usable energy molecule of the cell.

Electron Carriers (NADH and FADH2) : These molecules act like taxis, picking up high-energy electrons during Glycolysis and the Krebs Cycle and delivering them to the Electron Transport Chain.

Oxygen's Role: Oxygen acts as the final electron accepting at the end of the ETC, combining with electrons and hydrogen  to form water. Without oxygen, the whole chain backs down and stops.

Mitochondria: Often called as the "powerhouse of the cell" because the majority of ATP production occurs in this organelle.

All food (carbohydrates, fats, proteins) must be broken down into molecules that can enter one of these three stages to generate energy. Cellular respiration and photosynthesis are complementary processes that form a cycle. Photosynthesis uses Carbon dioxide and water to make Glucose, which are then used as inputs for cellular respiration.

From the CrashCourse, I learned that mitochondria really are the powerhouse of a cell, their hard work is transferring energy to food and oxygen, we need these even I'm simple things such as texting your friend, doing your hobbies and studying. This is important because we need energy to live and to do the things we want to do and don't, and that's why they're important.

I learned that cellular respiration is the process by which cells produce energy from glucose and oxygen. It happens in the mitochondria and produces ATP, the main energy source of the cell. The process includes three stages: glycolysis, the Krebs cycle, and the electron transport chain. Oxygen is very important because it helps release large amounts of energy, while carbon dioxide and water are the waste products. Overall, the lesson taught me how essential cellular respiration is for life and how it powers every cell in living organisms.

I learned from watching two videos that it explains aerobic cellular respiration in eukaryotic cells it converts the chemical into energy stored in food but the main goal in both videos is to make ATP

In Glycolysis it occurs in the cytoplasm it converts glucose into pyruvate and in Kreb cycle it occurs in the mitochondrial matrix it further breaks down the pyruvate derivatives and in electron transport chain it occurs in the inner mitochondrial membrane this is the oxygen requiring step where the coenzymes power a proton gradient to drive the ATP and producing the vast majority of the ATP

After watching the videos I learned that:

Cellular respiration has the opposite formula of photosynthesis. Photosynthesis product is glucose, while cellular respiration breaks down glucose to make ATP (Adenosine Triphosphate).

Plants can do both photosynthesis and cellular respiration.

If your ATP (Adenosine Triphosphate)stops producing it can be deadly because it is the main source of energy in every cell in your body.

Energy is used to power important cellular processes like making sure our body maintains homeostasis or keeps our body regulated with the right balance of stuff that we need.

The average human needs to use over a hundred pounds of ATP a day.

Humans and animals are aerobic organisms as we need oxygen to live, but there are some organisms like bacteria that don't need oxygen to release and store energy which is called anaerobic respiration, to add, fermentation is a process that doesn't require oxygen.

learned that cellular respiration is the essential process our cells use to convert the food we eat into usable energy, called ATP. This process primarily happens in the mitochondria, which are the powerhouses of the cell. Without ATP, our bodies couldn't perform any functions, from thinking to moving.

The whole process has three main steps:

· Glycolysis: This is the first round, happens in the cell's jelly-like cytoplasm. It breaks glucose down and gets a little bit of ATP to start the party.

· Krebs Cycle: This is the second stage, where things get serious. It happens in the mitochondria and breaks everything down even more, releasing CO2 (which we breathe out) and making a bunch of energy-packed molecules.

· Electron Transport Chain: This is the grand finale! It uses those energy-packed molecules and oxygen to create a TON of ATP. This is why we need to breathe oxygen constantly it's the key to making most of our en

ergy.

ATP stand for ' Adenosine Triphosphate'

glycolysis (oocurs cytoplasm) it broke down glucose into two molecules of pyruvate.

krebs cycle (occurs mitochondrial matrix) it breaks down pyruvate to releasing carbon dioxide makes two more ATP and produces NADH.

Electric transport chain (ETC), the energy is used to pump protons creating gradient. FINAL STAGES

I discovered that cellular respiration isn't only a process it's what sustains us and keeps us going every second. It generates the energy that makes all that our body does possible, and learning about it makes me realize how crucial healthy cells and mitochondria are to our health
