Question

Compared to aerobic respiration, anaerobic respiration

a
does not produce as much ATP and comes into action as an energy backup for aerobic organisms.
b
does not require oxygen and produces oxygen and glucose as forms of stored energy that are utilized by the cell.
c
requires oxygen and can produce products such as lactic acid or alcohol.
d
produces 38 ATP molecules per reaction and generates 70% more energy.

Answer 1

The correct answer is:

**a** does not produce as much ATP and comes into action as an energy backup for aerobic organisms.

Anaerobic respiration produces significantly less ATP compared to aerobic respiration and is used by organisms when oxygen is scarce or during high-intensity exercise when the oxygen supply is inadequate.
