Work is applying force to move or change something. Something that has energy can apply force because of this. There are 6 main types of energy: chemical, thermal, sound, light (or radiant), mechanical, and electrical. There are many other types of energy, but those 6 are the most common ones.]]> 2022-03-10 18:49:48 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2088967155 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2088971453 Mechanical: Energy that an object possesses due to its motion or position. An example of this is a hammer getting ready to hammer a nail.
Chemical: Energy that is stored within the bonds of atoms. It holds the bonds together. An example of this is food, because when it is digested, chemical energy is released.
Light (Radiant): Energy that is carried by light. This is usually referring to visible light. An x-ray, radio waves, and UV lights are all examples of this.
Electrical: Energy carried by charged particles. Electrical devices and appliances, like your cell phone, or an appliance in your home, can harness this energy by connecting to a circuit.
Thermal: Associated with temperature. A hot object has more thermal energy than a cold object.
Sound: Sound energy is energy carried by sound waves. Sound waves travel through matter (solids, liquids, or gases), and the energy is created by vibrations.]]> 2022-03-10 18:52:24 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2088971453 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2088985050 Aerobic respiration is a process in which energy is created from food molecules. During this process, oxygen is consumed and carbon dioxide is produced. In other words, carbon dioxide is produced in the presence of oxygen. 
Its chemical equation is:

This type of cellular respiration takes place in the anaerobes. In the anaerobes, energy is released from glucose and other foods WITHOUT oxygen.

Anaerobic respiration occurs in a lack of oxygen and less frequently than aerobic respiration. ]]> 2022-03-11 19:23:41 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2091001926 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2091009655 Anaerobic Respiration:

Many cells have varying levels of mitochondria in them. The goal of cellular respiration is to create energy. The energy is produced by converting chemicals within the cell. The conversion process creates energy (ATP). As mentioned before, some different cells have different amounts of mitochondria because they need more energy. For example, muscles, livers, and kidneys have high levels of mitochondria because they need more energy.]]> 2022-03-14 17:32:59 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2094354484 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2094384775 Baker's yeast is commonly used in the lab because it is cheap, its genetic material is easy to manipulate, and most researchers already know a lot about it. It is also easy to grow overnight, because yeast grows quickly. In the presence of oxygen, the baker's yeast changes sugars from a carbohydrate into carbon dioxide, which inflates air bubbles in the dough that allows bread to rise. When active yeast has both sugar and oxygen available, it "breathes" by a process called aerobic respiration.]]> 2022-03-14 17:48:02 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2094384775 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2096314424 Lactic acid fermentation usually occurs in muscle cells. It is the process in which glucose is broken down and changed into pyruvic acid, which is converted into lactic acid and helps with energy for cellular activities. Two main products that are made using this process are cheeses and yogurts. Lactic acid fermentation occurs in the presence of oxygen. In the process of alcoholic fermentation, the glucose molecule is changed into two pyruvate molecule, which gets converted into ethanol and cellular energy afterwards. Oxygen is not required for alcoholic fermentation. This process is mainly used in beverage factories, like beer production factories.

Differences:
-Lactic acid fermentation usually occurs in muscle cells of humans for energy, but alcoholic fermentation usually occurs in cells of yeast. 
-The lactic acid fermentation process is done in the cytosol when oxygen is present, while alcoholic fermentation is done in the cytosol but in the absence of oxygen. 
-The lactic acid fermentation is used to produce lactic acid and cellular energy, while alcoholic fermentation is used for making alcohol and carbon dioxide with the necessary cellular energy.

Similarities
-Both fermentation processes occur in an anaerobic environment
-Both produce some type of energy
-Both processes occur in the cytosol]]> 2022-03-15 16:08:57 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2096314424 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2096504544 Qualitative data is data that is shown in the form of words, objects, observations, pictures, and symbols.

For procedure one, the temperature was cold, and for procedure two, the temperature was warm. The independent variable is a variable that is changed or manipulated for the experiment.  The controls in this experiment were the amounts of yeast, sugar, and water that were added to the cups that we put the balloons over. The controls are things that are not affected by the independent variable, which is why the balloon is not a control, because the water temperature, which was the independent variable, affected the balloon.]]> 2022-03-15 17:57:02 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2096517221 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2096522389 This experiment was a closed system experiment. I know this because the cups we were experimenting with were sealed due to the balloons, and all the carbon dioxide that was produced while the yeast was reacting to the sugar and water.

During procedure 2, the one with the warm water, more carbon dioxide was produced in the 13 minutes that we had to test our experiments than in procedure 1, which had colder water.
E: After the 13 minutes, the circumference of the balloon for procedure 1 was 5 cm, and the circumference of the balloon for procedure 2 was 8 cm. 
R: From this evidence, we can easily tell that the warm water sped up the process of cellular respiration (fermentation) because more carbon dioxide was produced in procedure 2 than procedure 1 in the 13 minutes we timed it.]]> 2022-03-16 17:54:15 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2098559531 951785 https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2098565125 After completing this lab and seeing the results of procedures 1 and 2, two additional questions I have that I may want to experiment with in the future are: 

1. What exactly does yeast contain that makes it easy to produce carbon dioxide to make bread fluffy and the little air bubbles that we see in the bread?

2.  Since the cellular respiration process is significantly slower with a water temperature that is closer to room temperature, what would happen to the experiment if we used freezing cold water?]]> 2022-03-16 17:57:15 UTC https://padlet.com/951785/rfvre8qddc8q5rn1/wish/2098565125
