The ability of an enzyme to discriminate between two very similar substrates is based on the precise three-dimensional shape and chemical properties of its active site, a property known as

A. Catalytic power
B. Specificity
✓
C. Reversibility
D. Sensitivity to temperature

📝 Explanation

Specificity is the ability of an enzyme to choose exactly one substrate from a pool of similar molecules. This is due to the exact complementary fit and specific chemical interactions (ionic, H-bonding, hydrophobic) between the substrate and the R-groups lining the active site.
