What enables competitive inhibitors to bind to a specific enzyme? The efficiency of an enzyme's activity is often measured by the turnover rate, which measures the number of molecules of compound upon which the enzyme works per molecule of enzyme per second. D) amide groups do not participate in hydrogen bonding interactions. How does a noncompetitive inhibitor reduce an enzyme's activity? This makes the correct answer D. "Coenzyme" is a term for small organic molecules that bind to enzymes to aid in the catalytic reaction. B) It is activated by ATP. Assume you are working for a chemical company and are responsible for growing a yeast culture that produces ethanol. What does oxygen get reduced to at the end of the electron transport chain? Enzymes are specific biological catalysts that can not be … (It has covalent bonds holding it together). Learn more about enzymes in this article.
