•When oxygen is available, the pyruvate can be converted to acetyl-CoA and enter the
Krebs Cycle, where the acetyl-CoA will be completely oxidized and generate ATP through oxidative
phosphorylation.
•Fermentation is much less efficient than oxidative phosphorylation in making ATP, creating
only 2 ATP per
glucose while oxidative phosphorylation creates 36 ATP per glucose in mammalian cells.
•However anaerobic respiration
produces ATP 100 times faster than aerobic respiration.
