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

During an enzyme-catalyzed reaction, increasing substrate concentration from zero to the saturation level primarily increases the reaction rate because

A. The activation energy of the substrate increases
B. The probability of enzyme-substrate complex formation increases
✓
C. The enzyme molecules multiply
D. The enzyme becomes more stable

📝 Explanation

More substrate molecules increase the frequency of effective collisions with enzyme active sites until saturation is reached.

📖 Additional Information

  • The activation energy of the substrate increases
  • The probability of enzyme-substrate complex formation increases
  • The enzyme molecules multiply
  • The enzyme becomes more stable

More substrate molecules increase the frequency of effective collisions with enzyme active sites until saturation is reached.
