Compared to aerobic respiration, anaerobic respiration

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