Answer #1

3. Acetyl-Co-A

  • In the conversion of pyruvate to acetyl CoA, each pyruvate molecule loses one carbon atom with the release of carbon dioxide
  • During the breakdown of pyruvate, electrons are transferred to NAD+ to produce NADH, which will be used by the cell to produce ATP.
  • In the final step of the breakdown of pyruvate, an acetyl group is transferred to Coenzyme A to produce acetyl CoA.
  • acetyl CoA: a molecule that conveys the carbon atoms from glycolysis (pyruvate) to the citric acid cycle to be oxidized for energy production.

    In glycolysis, one glucose molecule yields pyruvates, ATP and NADH. Depending on the system used to shuttle the electrons from NADH into mitochondria, these NADH become NADH or FADH2. Converting the pyruvate(s) into acetyl-CoA's produces 2 NADH. One pyruvate/Two pyruvates pass(es) through the citric acid cycle starting with acetyl-CoA produces GTP, FADH2, and NADH. In the electron transport chain, each FADH2 generates ATP and each NADH ATP.
