Question

The synthesis of an amino acid follows this pathway: precursor A > intermediate B > amino acid C. Each reaction is catalyzed by a different enzyme. This metabolic pathway is controlled by feedback inhibition with amino acid C inhibiting the conversion of precursor A to intermediate B. Amino acid C acts as a _____ of the first enzyme in the pathway.a. substrate

b. competitive inhibitor
c. catalyst
d. noncompetitive inhibitor

Answer 1

The correct answer is the D option noncompetitive inhibitor

Step-by-step explanation:

Non-competitive inhibition is a type of inhibition that reduces the maximum rate of a chemical reaction without changing the apparent bonding affinity of the catalyst to the substrate.
