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

During enzyme-catalyzed reactions, extremely low temperatures generally produce

A. Complete destruction of the enzyme
B. Reduced reaction rate without permanent damage to the enzyme
✓
C. Permanent inactivation of the active site
D. Increased catalytic efficiency

📝 Explanation

Low temperature decreases molecular motion and collision frequency. The enzyme usually regains normal activity when returned to its optimum temperature.

📖 Additional Information
