Question

what is the main difference between aerobic respiration and anaerobic respiration? aerobic respiration requires oxygen to proceed, but anaerobic respiration does not. aerobic respiration occurs during photosynthesis, but anaerobic respiration occurs during cellular respiration. aerobic respiration produces atp, but anaerobic respiration does not. aerobic respiration involves glycolysis, but anaerobic respiration does not.

Explanation:

Aerobic respiration uses oxygen as the final electron - acceptor and occurs in the presence of oxygen, while anaerobic respiration occurs in the absence of oxygen and uses other electron - acceptors like nitrate or sulfate. Both aerobic and anaerobic respiration produce ATP, both involve glycolysis, and respiration (both aerobic and anaerobic) is a part of cellular respiration, not related to photosynthesis in the way described in the options.

Answer:

A. Aerobic respiration requires oxygen to proceed, but anaerobic respiration does not.
