What is the main difference between aerobic and anaerobic respiration? What cells perform anaerobic respiration? Compare the amount of ATP released by both aerobic and anaerobic respiration.
The fundamental difference between aerobic and anaerobic respiration is the usage of oxygen in the process of cellular respiration. Aerobic respiration, as the name suggests, is the process of producing the energy required by cells using oxygen.
Key points. Respiration is a chemical reaction which occurs in all living cells, releasing energy from glucose. Aerobic respiration occurs with oxygen and releases more energy but more slowly....
Aerobic respiration is much more efficient than anaerobic respiration. One molecule of glucose can generate up to 38 molecules of ATP if aerobic respiration is used. In contrast, only 2 molecules of ATP are generated in anaerobic respiration.
This process begins with glycosis, which breaks down glucose into ATP, but the presence of oxygen increases the amount of ATP a cell can produce at the cost of damaging the cell slightly. Whether a cell uses aerobic vs anaerobic respiration will depend on whether oxygen is available; aerobic respiration uses oxygen, while anaerobic respiration ...
Aerobic respiration is 19 times more effective at releasing energy than anaerobic respiration because aerobic processes extract most of the glucose molecules' energy in the form of ATP, while anaerobic processes leave most of the ATP-generating sources in the waste products.
Aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient but allows survival in habitats that lack oxygen.
