Q

Pyruvate

A

three-carbon sugar that can be decarboxylated and oxidized to make acetyl CoA, which enters the citric acid cycle under aerobic conditions; the end product of glycolysis.

Q

Citric- Acid Cycle

A

(Kreb’s Cycle) in matrix of mitochondria : NAD+ → NADH and FAD → FADH2 (About 38 ATPs total produced).
