Question

an enzyme catalyzes a reaction in a way that results in a lower activation energy. what is the significance of a lower activation energy? it increases the rate at which enzymes are consumed. it slows the reaction, preventing metabolic mistakes. it increases the rate of a cellular reaction. it reduces the energy expenditure of the cell.

Explanation:

Activation energy is the energy barrier for a reaction to occur. Enzymes lower it, allowing reactant molecules to more easily reach the transition - state and react. This leads to an increased reaction rate without changing the energy expenditure of the cell or consuming enzymes at a faster rate. Slowing the reaction is not the result of lower activation energy.

Answer:

It increases the rate of a cellular reaction.
