286770 In alcoholic fermentation:

1 oxygen is the electron acceptor.

2 triose phosphate is the electron donor while acetaldehyde is the electron acceptor.

3 triose phosphate is the electron donor while pyruvic acid is the electron acceptor.

4 there is no electron donor.

286773 In alcoholic fermentation, $N A D^{+}$ is produced during the:

1 reduction of acetyldehyde to ethanol.

2 oxidation of glucose.

3 oxidation of pyruvate to acetyl CoA.

4 hydrolysis of atp to ADP.

Explanation:

(a) Alcoholic fermentation is a process in which molecules such as glucose etc. are converted into cellular energy and thereby produce ethanol and carbon dioxide as metabolic waste products. During alcoholic fermentation, $NA D^{+}$ is produced when acetaldehyde is reduced to ethanol.
