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

During an experiment, increasing temperature from 35°C to 40°C causes a higher reaction rate. The most appropriate explanation is

A. More enzyme molecules are synthesized immediately
B. Increased molecular collisions between enzyme and substrate
✓
C. Substrate molecules become permanently activated
D. The enzyme changes its amino acid sequence

📝 Explanation

Higher temperature increases kinetic energy, producing more frequent effective collisions until the optimum temperature is reached.

📖 Additional Information

  • More enzyme molecules are synthesized immediately
  • Increased molecular collisions between enzyme and substrate
  • Substrate molecules become permanently activated
  • The enzyme changes its amino acid sequence

Higher temperature increases kinetic energy, producing more frequent effective collisions until the optimum temperature is reached.
