MDCAT Biology QUESTION #7759
Question 1

Enzymes accelerate chemical reactions by:

  • Changing equilibrium toward substrate
  • Increasing activation energy
  • Increasing substrate concentration
  • Lowering activation energyāœ”ļø
Correct Answer Explanation

Enzymes lower the activation energy (Eā‚) of a reaction, allowing more molecules to reach the transition state at a given temperature. They do not alter equilibrium.
