Question

The last product in a reaction pathway often regulates the activity of the first enzyme in the branch of the pathway that is unique to its production when the concentration of the product gets very high. Because the structure of the product is very likely to differ substantially from that of the the enzyme's normal substrate, this type of regulation is most likely:
Competitive inhibition
Competitive activation
Allosteric inhibition
Allosteric activation
Covalent modification

Explanation / Answer

Answer: Allosteric inhibition

The final end-product molecule fits in the allosteric site of the enzyme thereby inhibiting the enzyme from binding to its substrate. This is called Allosteric inhibition.

Competitive inhibition refers to a kiind of inhibition of enzyme where the inhibitor is similar to the substrate and competes for the active site.
