NameShort Answer:Alcohol dehydrogenase catalyzes the oxidation of an alcohol to the next higheststate of oxidation, an aldehyde. How does this partially explain the toxicity of methanol?Page 5 of 5Most organisms use D-glucose as a primary metabolic fuel. Predict what would happen ifonly L-glucose were available.How can an enzyme produce a chiral product from a nonchiral or prochiral substrate?How can the water bound to a metal ion cofactor contribute to catalysis?Explain the advantage for an enzyme to strongly bind the transition state structureof the reaction it catalyzes.Give an explanation for the inability of a zymogen to catalyze a reaction.Why must an enzyme be returned to its original state at the conclusion of a reaction?How is it possible to determine the structure of an enzyme-substrate complex by X-raycrystallography when the reaction is over so quickly and the X-ray analysis takes at leastseveral minutes?
