Question

multiple choice the reactants of one chemical reaction are the products for the next reaction once an enzyme catalyzes the first reaction, a series of reactions that follow proceed from start to finish without enzymes the products of one chemical reaction are the reactants for the next reaction the enzymes involved are not close to each other

Explanation:

In a metabolic pathway (a series of chemical reactions in a cell), the products of one reaction serve as the reactants for the next reaction. The first option has reactants as products for the next, which is incorrect. The second option is wrong because each reaction in a pathway (usually) needs an enzyme. The fourth option is incorrect as enzymes in a pathway are often organized close together (e.g., in a multienzyme complex or in the same cellular location) to facilitate the sequence. So the correct statement is that the products of one chemical reaction are the reactants for the next reaction.

Answer:

the option with "the products of one chemical reaction are the reactants for the next reaction" (the third option among the listed choices)
