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

A decrease in reaction rate at temperatures above the optimum is primarily associated with

A. Reduced substrate concentration
B. Loss of the enzyme's tertiary structure
✓
C. Increased enzyme concentration
D. Formation of additional active sites

📝 Explanation

Excessive heat disrupts the three-dimensional conformation required for catalytic activity, resulting in denaturation.

📖 Additional Information

  • Reduced substrate concentration
  • Loss of the enzyme's tertiary structure
  • Increased enzyme concentration
  • Formation of additional active sites
