Oxygen
Because cellular respiration occurs in the presence of oxygen.
Because it requires oxygen
The steps of cellular respiration is different when it is anaerobic respiration compared to aerobic respiration. The main difference is because aerobic respiration uses oxygen and anaerobic uses other elements but the other steps are similar.
Cellular respiration, or aerobic cellular respiration, is exergonic because energy is released from the breakdown of glucose and therefore the products have less energy then the starting substance.
Aerobic cellular respiration produces a net gain of 36 ATP per glucose molecule. Anaerobic respiration produces a net gain of 2 ATP per glucose molecules.Aerobic cellular respiration produces 15 times more energy from sugar than anaerobic cellular respiration. :-)
aerobic
Cellular respiration is called an aerobic process because it requires oxygen to produce energy in the form of ATP. The final stages of cellular respiration, the electron transport chain and oxidative phosphorylation, can only occur in the presence of oxygen. The term "aerobic" refers to the use of oxygen in a process.
Cellular respiration is called an aerobic process because it requires oxygen to produce energy in the form of ATP molecules. During aerobic respiration, glucose is broken down in the presence of oxygen to generate ATP through a series of biochemical reactions in the mitochondria of cells.
Aerobic respiration is the type of cellular respiration that requires oxygen. This process involves the release of glucose for energy.Aerobic respiration requires oxygen to be present because it is the final electron acceptor at the end of the electron transport chain. If it is not present, then the electron can not go through the chain and fermentation will cycle instead. Fermentation is much more inefficient in producing ATP (a differenence of 32 ATP).
Aerobic respiration produces more energy compared to anaerobic respiration. This is because aerobic respiration utilizes oxygen to fully break down glucose, resulting in more ATP (energy) production per glucose molecule. Anaerobic respiration, on the other hand, does not require oxygen and results in lower ATP production.
If an organism performs cellular respiration without oxygen, it undergoes anaerobic respiration. This process yields less ATP compared to aerobic respiration and produces lactic acid or ethanol as byproducts. Anaerobic respiration is less efficient because oxygen is not available to act as the final electron acceptor in the electron transport chain.
Because anaerobic respiration releases less energy than aerobic respiration.
