- 22. Multiple Choice
Why are aerobic reactions more efficient for cellular metabolism than anaerobic reactions?
Aerobic reactions build up lactic acid, which contains more stored energy.
Aerobic reactions are faster than anaerobic reactions and generate more ADP.
Aerobic reactions do not require oxygen to build protein molecules.
Aerobic reactions break down sugars more completely and produce the maximum amount of ATP.
