  3. This is one of many examples where synthesis and breakdown have branchpoints in their respective pathways.
  4. Of the above list, only the PFK step is different, catalyzed by fructose-1.6-bis phosphatase.
  5. This pattern of control coordinates the branchpoint at the PFK step.
  6. Another example of control at a branchpoint; in this case the rapidly-responding phosphorylation state of the two enzymes is critical.
  All of the correct answers have a green check mark.
  Incorrect answers have the "red-lit" button next to your choice.
