22. At the end of glycolysis, pyruvate (3C) diffuses toward the mitochondrion. Before it enters the Krebs cycle, enzymes in the cytoplasm convert it to a 2-carbon molecule. These reactions include:
a. Coenzyme A joins the pyruvate, causing it to donate an energized electron and hydrogen ion to NAD+, making one NADH.
b. a molecule of CO2 is removed from the pyruvate - coenzyme A complex.
c. the 2-carbon molecule left over is known as Acetyl-CoA.
d. the Acetyl-CoA joins the Krebs cycle.
