Reflexive memory relies on the cerebellum and amygdala. Compare between aerobic respiration and anaerobic respiration. Aerobic respiration occurs in the presence oxygen, creates a maximum of 38 ATP, while anaerobic respiration occurs in the absence of oxygen, and creates a maximum of 2 ATP. Aerobic respiration has both substrate level and oxidative phosphorylation while anaerobic respiration has only substrate level phosphorlyation. Also, but use glycolysis.

In anaerobic respiration, the final electron acceptor is an organic molecule such as pyruvate or acetaldehyde, but in respiration, the final acceptor is oxygen.
