Which of the following would differ if you compared the sam reaction taking place with and without an enzyme?

a. the chemical energy of the reactants****
b. the chemical energy of the products
c. the energy required to start the reaction
d. the overall energy of the reaction

Look up the term activation energy...........I would go with answer choice c.

To determine the correct answer, let's first understand the role of enzymes in reactions. Enzymes are biological catalysts that increase the rate of chemical reactions by lowering the activation energy required to start the reaction. They do not alter the overall energy of the reaction or the chemical energy of the reactants or products.

Comparing the same reaction with and without an enzyme, the main difference would be option c, the energy required to start the reaction. Without an enzyme, the reaction would require a higher amount of energy (activation energy) to initiate. Enzymes facilitate the reaction by providing an alternative pathway that has a lower activation energy. Therefore, the energy required to start the reaction is reduced in the presence of an enzyme.

Therefore, the correct answer is c. the energy required to start the reaction.
