Pyruvate is the product of glycolysis, the first set of reactions in the metabolism of glucose. This pyruvate molecule can proceed to different processes, depending on the condition of the cell, particularly in the presence (aerobic) or absence (anaerobic) of oxygen.
There are several metabolic fates of pyruvate and those are all of the following EXCEPT:
A. Lactate is formed from pyruvate under anaerobic conditions.
B. Fermentation of pyruvate will result in the formation of ethanol and CO2.
C. Pyruvate is oxidized to lactate.
D. The purpose of converting pyruvate to lactate is to oxidize NADH to NAD+, since NAD+ is required for glycolysis to keep producing small amounts of ATP.
E. Acetyl CoA is formed from pyruvate under aerobic conditions.
