Answer #1

Ethanol + NAD^+ ---> acetaldehyde + NADH + H^+

The half reactions are:

(1) Ethanol ---------à Acetaldehyde + 2H^+ + 2e (oxidation)

(2) NAD+ + 2H+ + 2e- ------->NADH + H^+ (Reduction)

Ethanol is oxidized to acetaldehyde, because it loses e-

NAD+ is reduced to NADH, because it gain of e−

NAD is the oxidizing agent. (Oxidizing agent gains e− and therefore reduced during reaction)

Ethanol is the reducing agent. (Reducing agent loses e−and therefore oxidized during reaction)

Alcohol dehydrogenase (ADH) is a liver enzyme that catalyzes the oxidation of ethanol to acetaldehyde. The catalyzed reaction in the liver is zero-order with a rate constant of 0.17 molh−1. Halogenated hydrocarbons act as inhibitors to the ADH by binding strongly to the enzyme. The halogenated hydrocarbons can persist in the liver for days following exposure. Suppose that a worker who is exposed to halogenated hydrocarbons leaves work with 40 % of their ADH inhibited. The worker decides to have...

4. A biochemist carries out an enzymatic activity assay of alcohol dehydrogenase at 37°C using 200 uM NADH and an excess of substrate and allows the reaction to proceed to equilibrium. At equilibrium, the concentration of NADH is measured to be 1.1 x 10–8 uM while the concentration of NAD+ is calculated to be 200 uM. What is the biochemical free energy change (deltaG'o) of the reaction system for converting NADH to NAD+, in kJ/mol? (R=8.314J/mol*K)
