So Where does Cellular Respiration Occur In

# data[].attributes.body
Cellular respiration occurs only in the mitochondria of animal cells. This includes mammals, reptiles, humans, birds, all marine life and bacteria cells. All living things that are able to move, grow and not produce food by themselves are able to respire. Non producers (not a plant) get their glucose from the food they consume. Cellular respiration does not occur in plants because their source of glucose comes from photosynthesis when the chloroplast (plant cell organelle) absorbs the sunlight. Oxygen, carbon dioxide, water and sunlight is mixed to produce glucose. (ehow, Edriaan Koening, 2018)

Why is Cellular Respiration So Important? 

# data[].attributes.body
Cellular respiration is vital for maintaining life because it provides all living things the energy to do the necessary actions to maintain life. Without cellular respiration there would be no life for non producers.

Here is a crash-course video link which explains what cellular respiration is and how is occurs in greater detail.

Glucose is transported to the mitochondria and then goes the the Krebs cycle where it is broken down by oxygen and is then turned into NADH. The NADH is taken into the electron transport chain where the electrons from the NADH is taken way to from positive hydrogen ions which mixes with the oxygen to produce water as a waste product. The remaining products left from the NADH is turned into ATP which releases energy to the cell. Carbon dioxide is also a waste product from the electron transport chain. (khan academy, 2018)

There are two types of cellular respiration, these different types of respiration are called anaerobic and aerobic respiration. Anaerobic respiration occurs in the cells where a simple sugar, glucose is broken down in the absence of oxygen. Typically glucose is broken down with oxygen to release energy to the cells, however when the body is in need of quick releases of energy it produces lactic acid to metabolise (break down) the glucose. All of the reactions of breaking down glucose occur in the mitochondria which is an organelle (organs inside a cell) and commonly referred to as the power house of the cell as it supplies energy to the cells by metabolising glucose. Aerobic respiration occurs similarly to anaerobic respiration as it happens in the mitochondria as well, however it breaks down the glucose with oxygen to be released to the cell. No lactic acid is produced during the reaction. The worded chemical reaction for aerobic cell respiration is: glucose + oxygen -> carbon dioxide + water. The chemical respiration for aerobic cell respiration is: C6H12O6 + 6O2 -> C6O2 + 6H2O. The word equation for anaerobic respiration is similar to aerobic respiration but it does not have oxygen to break down the glucose. The word equation is Glucose -> lactic acid + carbon dioxide + energy.  The chemical equation is 6CO2 + 6H2O -> C6H12O6 + 6O2.

What is cellular respiration?
Cell respiration refers to the way cells release energy from the foods we consume that power our body and process to live.
