Which one of the following is an accurate description of the role of enzymes in an enzyme-catalyzed reaction? Select one: A. Enzymes bind a transition state intermediate, such that it cannot be converted back to substrate. B. Enzymes ensure that all substrate molecules are converted to product. C. Enzymes ensure that the product is more stable than the substrate. D. Enzymes increase the rate at which substrates are converted into product. E. Enzymes make the free-energy change for a reaction more favorable.
