Question

In alcoholic fermentation

• A. Triose phosphate is the electron donor, while acetaldehyde is the electron acceptor.
• B. Triose phosphate is the electron donor, while pyruvic acid is the electron acceptor.
• C. There is no electron donor.
• D. Oxygen is the electron acceptor.

Answer 1

The correct option is A Triose phosphate is the electron donor, while acetaldehyde is the electron acceptor.

Alcoholic fermentation also referred to as ethanol fermentation, is a biological process in which elements, such as glucose, fructose and sucrose are converted into cellular energy and thereby produce ethanol and carbon dioxide as a metabolic waste product.

During fermentation, glucose undergoes glycolysis and yields pyruvic acid, which then converted to acetyl CoA. Then glyceraldehyde phosphate is produced, which then converted to acetaldehyde and this acetaldehyde converted into ethanol. So, in alcohol fermentation triose phosphate is the electron donor, while acetaldehyde is the electron acceptor.

So, the correct answer is option A.
