    False.
  3. The end product of glycolysis is
    pyruvate.
  4. Nonprotein substances that assist enzymes are called
    coenzymes.
  5. The electron transport chain is a series of electron carriers in the cristae of the mitochondria.
    True.
  6. Which of the following is true regarding glycolysis?
    Glycolysis results in a net gain of 2 ATP.
  7. Which does not occur in the preparatory reaction?
    An acetyl group is attached to citric acid
  8. During the citric acid cycle, the breakdown of each glucose molecule produces 3 NADH molecules which donate electrons to the electron transport chain.
    False.
  9. Substrate-level ATP synthesis occurs in
    glycolysis and the citric acid cycle.
