nmdcat.online July 11, 2026

During enzyme action, the optimum pH differs among enzymes because

A. All enzymes possess identical active sites
B. Different enzymes contain different ionizable amino acid residues
✓
C. All enzymes contain equal numbers of peptide bonds
D. Every enzyme has identical substrate specificity

📝 Explanation

Each enzyme has a unique active site with specific amino acid residues that require particular ionization states for maximum catalytic efficiency.
