An enzyme ______ the activation energy required for a chemical reaction.

  • A.increases
  • B.converts
  • C.lowers
  • D.catalyzes

Answer: C

Correct answer: lowers

An enzyme lowers the activation energy - the barrier a reaction must climb before it can proceed - by binding the substrate in a way that stabilises the transition state. What it does not change is the equilibrium or the overall free energy change: it makes the reaction faster, not more favourable.
