nmdcat.online July 11, 2026

In biological systems, enzymes adapted to different tissues exhibit different optimum pH values because

A. All tissues possess identical chemical environments
B. Catalytic amino acid residues require different ionization states
✓
C. The substrate concentration differs permanently
D. Protein synthesis varies with pH

📝 Explanation

Each enzyme has unique active-site residues whose catalytic function depends on a specific protonation state.
