MCAT Question of the Day

    Q:

    		 Ethanol (alcohol) is metabolized in the body through several important enzymes. Ethanol is converted to acetaldehyde via alcohol dehydrogenase, from which it is converted to acetic acid by aldehyde dehydrogenase. Inefficiency of the aldehyde dehydrogenase enzyme can result in a buildup of intermediates, resulting in headache, red flushing of the face, and other negative effects. Acetic acid can finally be converted to acetyl CoA by a separate enzyme. Which of the following is true regarding this phenomenon?
    		 

    A

    		 It can be alleviated through an increase in amount of alcohol dehydrogenase.

    B

    		 In populations which experience these symptoms due to enzyme inefficiency, there is a decrease in the overall concentration of acetaldehyde.

    C

    		 The end-products of ethanol metabolism can enter glycolysis to create ATP.

    D

    		 There would be decreased acetic acid concentrations in people with this enzyme inefficiency.
