Explanation:
Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
Detailed explanation-2: -These enzymes can carry out as many as 106-107 reactions per second. At the opposite extreme, restriction enzymes limp along while performing only ≈10-1-10-2 reactions per second or about one reaction per minute per enzyme (BNID 101627, 101635).
Detailed explanation-3: -Coenzymes and inorganic cofactors may be necessary for an enzyme to work, and if there aren’t enough of them, then the overall reaction rate will be slow.
