Metabolic Fate of Pyruvate


Pyruvate, produced during glycolysis, has several metabolic fates in animals and plants depending in part upon oxygen conditions of the cell. Complete the following statements to correctly demonstrate the fate of pyruvate and the products produced under the given conditions.

Under anaerobic conditions, pyruvate is converted to

in animals and to

and ${ CO }_{ 2 }$ in plants;

is regenerated in both.

Under aerobic conditions in animals or plants, pyruvate dehydrogenase catalyzes the conversion of pyruvate to


is evolved, and

is produced.
