Enzymes are able to speed up the rate of a reaction by
A) carrying substrates closer together.
B) binding substrates to a membrane.
C) producing more enzymes.
D) lowering the energy needed for the reaction to proceed.
E) producing more substrate.

Question

Quizplus · Accepted Answer

Enzymes lower the activation energy required for a reaction to occur, which accelerates the reaction rate. They do this by stabilizing the transition state of the reaction, allowing it to proceed more quickly. Enzymes do not typically carry substrates closer together or produce more substrate or enzymes, and they do not bind substrates to a membrane.
