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

A decrease in substrate concentration after prolonged reaction causes the reaction rate to decline because

A. Active sites become permanently damaged
B. Fewer substrate molecules collide with enzyme molecules
✓
C. The enzyme loses its amino acid sequence
D. Product molecules destroy enzymes

📝 Explanation

As substrate becomes depleted, enzyme-substrate complex formation decreases, reducing the overall reaction rate.

📖 Additional Information

  • Active sites become permanently damaged
  • Fewer substrate molecules collide with enzyme molecules
  • The enzyme loses its amino acid sequence
  • Product molecules destroy enzymes

As substrate becomes depleted, enzyme-substrate complex formation decreases, reducing the overall reaction rate.
