Multiple choice

Enzymes act on the substrate in several ways, except by

  1. lowering the energy of the transition state of the substrate

  2. increasing the reaction entropy change

  3. providing an alternative pathway

  4. lowering the activation energy
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

They reduce the reaction entropy change by bringing substrates together in the correct orientation to react. Considering ΔH‡ alone overlooks this effect.
