Fermentation vs. Anaerobic Respiration

Anaerobic respiration begins the same way as aerobic respiration and fermentation. The first step is still glycolysis, and it still creates 2 ATP from one carbohydrate molecule. However, instead of ending with glycolysis, as fermentation does, anaerobic respiration creates pyruvate and then continues on the same path as aerobic respiration.
