The correct match between Item I and Item II is

Item I
A. Allosteric effect
B. Competitive inhibitor
C. Receptor
D. Poison

Item II
P. Molecule binding to the active site of enzyme
Q. Molecule crucial for communication in the body
R. Molecule binding to a site other than the active site of enzyme
S. Molecule binding to the enzyme covalently

(A) $A \to R, B \to P, C \to Q, D \to S$ ✓ Correct
(B) $A \to P, B \to R, C \to Q, D \to S$
(C)A $\to R, B \to P, C \to S, D \to Q$
(D) $A \to P, B \to R, C \to S, D \to Q$

Answer: (A)

Solution

Matching each term with its definition: an allosteric effect is a molecule binding at a site other than the enzyme's active site; a competitive inhibitor binds at the active site itself; a receptor is a molecule central to communication within the body; and a poison binds to the enzyme covalently. These are the standard definitions of enzyme kinetics.
