Glycolysis - Medical Science

Q1:

Phosphofructokinase, the major flux-controlling enzyme of glycolysis is allosterically inhibited and activated respectively by

A ATP and PEP

B AMP and Pi

C ATP and ADP

D Citrate and ATP

ANS:C - ATP and ADP

Here, it is about inhiation and activation inhibited by ATP and activated by ADP when the substrate concentration increases the AT inhibit the enzyme and the concentration of substrate decreases the ADP activate the enzyme that's true citrate inhibits the enzyme but question is regarding activation and inhiation.
