In alcohol fermentation a) triose phosphate is the electron donor while acetyldehyde is the electron acceptor b) there is no electron donar c) oxygen is the electron acceptor d) triose phosphate is the electron donar while pyruvic acid is the electron acceptor.. explain the right answer in detail....

Dear Student,

The correct answer is option a) triose
 phosphate is the electron donor while acetaldehyde is the electron acceptor. 

Alcoholic fermentation is a biological process takes place in the absence of oxygen to derive cellular energy. In this, sugars such as glucose, fructose and sucrose are broken down into ethyl alcohol (ethanol) and carbon dioxide. 

In alcohol fermentation, the oxidation of glyceraldehyde 3-phosphate (triose phosphate) occurs which produces NADH. This NADH donates an electron and then the acetaldehyde gets reduced to ethanol and NAD+ is regenerated. Thus, triose phosphate is the electron donor while acetaldehyde is the electron acceptor. 


Regards
