The amount of ATP produced by anaerobic versus aerobic metabolism depends on the availability of oxygen. Cellular respiration can be anaerobic or aerobic respiration, depending on whether or not oxygen is present. Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose.
