Question

After glycolysis, the first step of ethyl alcohol fermentation requires

• A. dehydrogenation
• B. decarboxylation
• C. FAD reduction
• D. $M{n}^{+2}$ acceptance

Answer 1

The correct option is B decarboxylation

Alcoholic fermentation is a biochemical process in which sugars such as glucose and fructose are used to produce small amounts of ATP producing ethanol and $C{O}_2$ in the process.
In the first step after glycolysis, pyruvate is decarboxylated to form acetaldehyde, which is then reduced to form ethanol.
