Question
**Question 7** You are intensely focused on studying biochemistry and, because you are enjoying yourself so much, you forget to eat lunch and dinner. What happens to the fructose 2,6-bisphosphate levels in your hepatocytes, and what is the effect? - **A.** F2,6BP levels go down, leading to less activation of PFK-1 and reduced glycolysis, thus sparing glucose for the blood - **B.** None of the other answers is correct - **C.** F2,6BP levels go down because glycolysis is reduced, so PFK-1 produces less F2,6BP - **D.** F2,6BP levels go up because glycolysis is increased, so PFK-1 produces more F2,6BP - **E.** F2,6BP levels go up, leading to more activation of PFK-1 and increased glycolysis, thus using more glucose for fuel
