Which statement BEST describes how an enzyme lowers the activation energy of a reaction?
A) The enzyme covalently binds to the substrate, lowering its energy.
B) The enzyme chemically reacts with the substrate to make it more reactive.
C) The enzyme increases the temperature of the substrate, making it more reactive.
D) The substrate is held in the correct orientation for the reaction to occur.
E) All of the above describe how an enzyme lowers the activation energy.

Question

Quizplus · Accepted Answer

Enzymes lower the activation energy of a reaction by binding to substrates and orienting them in a way that makes the chemical reaction more likely to occur, without being consumed in the process. This does not necessarily involve covalent binding, chemical reaction with the substrate, or increasing the temperature.
