Question

Quizplus · Accepted Answer

During an enzymatic reaction, the enzyme and the substrate come together to form a temporary complex. The enzyme facilitates the reaction and then is released unchanged, ready to catalyze another reaction. Therefore, choices A, B, and C are incorrect. The formation of a permanent complex (choice D) is unlikely and not common in enzymatic reactions.
