In alcohol 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

Correct Answer: A

Solution :

During Alcoholic fermentation So triose phosphate is electron doner i.e. l,3BiPGAL during glycolysis oxidized to release electrons accepted by NAD to form \[NAD{{H}_{2}}\]During glycolysis \[1,3\text{ }BiPGAL\xrightarrow{{}}1.3BiPGA+2\text{ }NAD{{H}_{2}}+2NAD\]Now during alcoholic fermentation these \[NAD{{H}_{2}}\] reduce the aceteldehyde so aceteldehyde is electron acceptor
