Question

Which of the following is true of enzymes?

a. An enzyme is consumed during a chemical reaction.
b. An enzyme is converted to a product during a chemical reaction.
c. An enzyme lowers the energy of activation required for a given reaction.
d. An enzyme catalyzes a number of different chemical reactions.

Answer 1

Answer: Option C.

Enzymes lowers activation energy required for a given reaction.

Explanation:

Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.

Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
