The diagram below shows an enzyme and a substrate it can bind.

Question

enzyme, substrate, and active site
How does the structure of this enzyme help with its function?
A.
The enzyme's shape complements the substrate's shape, so it only catalyzes specific reactions.
B.
Since the enzyme is larger than the substrate, catalytic reactions can occur within the enzyme itself.
C.
Since the enzyme's shape matches the substrate's shape, it catalyzes only reverse reactions.
D.
The enzyme's active site is amorphous and can change its shape to fit any substrate.

Answer 1

A. The enzyme's shape complements the substrate's shape, so it only catalyzes specific reactions.

This allows the enzyme to specifically bind and catalyze a particular substrate, leading to efficient and precise enzymatic reactions.
