Question

Why is anaerobic respiration less efficient?
​

Answer 1

Answer:

Explanation:

Anaerobic respiration is a process in which energy is released from glucose without requiring oxygen. It is less efficient than aerobic respiration as it releases less energy than the energy released in aerobic respiration.

#note

Much less energy is released during anaerobic respiration than during aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt. This is the amount of oxygen needed to oxidise lactic acid to carbon dioxide and water.

Answer 2

Answer:

Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain. ... Therefore, anaerobic respiration is less efficient than aerobic.
