Question 8: Insulin action in (skeletal) muscle

Insulin regulates all of the following enzymes in liver. Which of these enzymes are also regulated by insulin in muscle?

  1. Glycogen synthase

  2. Glycogen phosphorylase

  3. phosphofructokinase-1 (PFK-1)

  4. phosphofructokinase-2 (PFK-2)

  5. glucokinase

Tutorial

This is essentially the same figure as for insulin action in liver (question 1 of this module), and the five enzymes in question are denoted with question marks. The key for arriving at the correct answer is to determine which enzymes are missing in muscle...


Insulin action in muscle (not liver!)
