4. The enzyme alcohol dehydrogenase catalyzes the oxidation of ethyl alcohol by NAD+ to give acetaldehyde plus NADH and a proton:

CH3CH2OH + NAD+ CH3CHO + NADH + H+

The rate of this reaction can be measured by following the change in pH. The reaction is run in 1 mL 10 mM TRIS buffer at pH 8.6. If the pH of the reaction solution falls to 8.4 after ten minutes, what is the rate of alcohol oxidation, expressed as nanomoles of ethanol oxidized per mL per sec of reaction mixture?

The human pathway for metabolizing alcohol starts with the enzyme alcohol dehydrogenase, which catalyzes the conversion of ethanol (C2H5OH) to acetaldehyde (CH3CHO). This is followed by the aldehyde dehydrogenase 2 (ALDH2, the enzyme of interest in this problem), which catalyzes the conversion of acetaldehyde and HS-CoA to acetyl-CoA (CH3CO–S–CoA). The TCA cycle starts and oxidizes the acetyl-CoA to CO2. Draw two diagrams of this pathway—one for an individual without AFS and another for an individual with AFS. How ALDH2 deficiency...

The enzyme glucose oxidase isolated from the mold Penicillium notatum catalyzes the oxidation of β-D-glucose to D-glucono-δ-lactone. This enzyme is highly specific for the β anomer of glucose and does not affect the α anomer. In spite of this specificity, the reaction catalyzed by glucose oxidase is commonly used in a clinical assay for total blood glucose –that is, for solutions consisting of a mixture of β-D-glucose and α-D-glucose. What makes it possible for this test to measure total blood...
