The enzyme phosphofructokinase-1 (PFK-1) catalyzes the 3rd reaction in glycolysi

Question

The enzyme phosphofructokinase-1 (PFK-1) catalyzes the 3rd reaction in glycolysis. When AMP concentrations are very high, AMP binds to PFK-1, activating it. This is an example of: 1) competitive inhibition 2) allosteric activation 3) allosteric inhibition 4) direct feedback inhibition 5) end-product inhibition 6) both allosteric inhibition and end-product inhibition The enzyme phosphofructokinase-1 (PFK-1) catalyzes the 3rd reaction in glycolysis.
