You are studying the enzyme alcohol dehydrogenase that catalyzes the following reaction:NAD+ + ethanol ? NADH + H+ + acetaldehydeA)You discover that mercury ion (Hg+) at a concentration of 1 mM inhibits the enzyme by 95%. You find by appropriate kinetic experiments that the enzyme's apparent Km for ethanol is the same in the presence and the absence of Hg+. What does this tell you about the kind of inhibition caused by Hg+? B)Explain how you, as a working biochemist, might discover whether or not this enzyme is allosterically regulated.
