BIO NMDCAT Factors that Affect the Rate of Enzyme Reactions
nmdcat.online July 11, 2026

Regarding enzyme activity, the optimum temperature represents the condition at which

A. Enzyme molecules are permanently stable
B. The rate of enzyme-catalyzed reaction reaches its maximum
✓
C. The enzyme becomes resistant to pH changes
D. The substrate concentration becomes limiting

📝 Explanation

Every enzyme has an optimum temperature where catalytic activity is highest. Above this temperature, the enzyme's three-dimensional structure begins to lose stability.

📖 Additional Information

  • Enzyme molecules are permanently stable
  • The rate of enzyme-catalyzed reaction reaches its maximum
  • The enzyme becomes resistant to pH changes
  • The substrate concentration becomes limiting

Every enzyme has an optimum temperature where catalytic activity is highest. Above this temperature, the enzyme's three-dimensional structure begins to lose stability.
