Question

During anaerobic respiration, ____________ ATP molecules are generated by the breakdown of 20 glucose molecules.

Options

• 80

• 60

• 40

• 20

Answer 1

During anaerobic respiration, 40 ATP molecules are generated by the breakdown of 20 glucose molecules.

Explanation:

The net gain of ATP during anaerobic respiration is 2 ATP per glucose molecule. Thus, during anaerobic respiration, the breakdown of 20 glucose molecules generates (2 X 20 ATP) 40 ATP molecules.
