Conversion of Pyruvate to Acetyl-CoA • Irreversible reaction • Loss of a CO 2 from pyruvate • NADH is produced in the process • Occurs in mitochondria • Requires thiamin (B1), FAD (B2), lipoic acid and CoA NAD + , CoA CO 2, NADH Pyruvate (3 C) Acetyl-CoA (2 C) Pyruvate dehydrogenase Know this reaction including cofactors & pyruvate
