Question

13 multiple choice 1 point what do enzymes do and how do they do it? enzymes release stored energy by breaking down carbon - hydrogen bonds stored in lipids. enzymes produce the products of the reaction by consuming the reactants. enzymes speed up the rate of chemical reactions by lowering the activation energy. enzymes work best at normal body temperatures, because if they get too hot they can denature. clear my selection

Explanation:

Enzymes are biological catalysts. They function by reducing the activation - energy barrier for chemical reactions, thus increasing the reaction rate. The other options are incorrect as enzymes don't release energy from lipids in the way described, don't produce products by consuming reactants in a non - catalytic sense, and the last option describes a condition for enzyme activity rather than what enzymes do and how.

Answer:

Enzymes speed up the rate of chemical reactions by lowering the activation energy.
