Fill in the blank
Ethanol will generate 1._______________ through the action of alcohol dehydrogenase, and this will 2.___________ formaldehyde back to 3.________, also through alcohol dehydrogenase. The 4.___________ formed can be metabolized further to acetate. Ethanol may also compete with methanol for binding to alcohol dehydrogenase.
LIST OF POSSIBLE WORDS:
oxidize
NAD+
methanol
acetaldehyde
formaldehyde
acetate
formate
NADH
reduce

Respuesta :

Answer:

  1. NADH
  2. reduce
  3. methanol
  4. acetaldehyde

Explanation:

Alcohol dehydrogenase(ADH) is a cystolic enzyme which is mainly found in liver,catalyze the break down of alcohol to aldehyde. This binding of alcohol to alcohol dehydrogenase releases electrons which is accepted by NAD+ to form NADH. The aldehyde that is formed is further oxidized to an acid by alcohol dehydrogenase 2.

Oxidation of ethanol by alcohol dehydrogenase will produce acetaldehyde, and NAD+ will be reduced to NADH in the process. This acetaldehyde is a toxic compound so it will be further oxidized to acetate by alcohol dehydrogenase 2 enzyme.

Formaldehyde can be reduced back to methanol in the presence of NADH by alcohol dehydrogenase.
