Biology Respiration in Plants NEET 2003

In alcohol fermentation : -

(1)Triose phosphate is the electron donor while acetaldehyde is the electron acceptorCorrect
(2)Triose phosphate is the electron donor while pyruvic acid is the electron acceptor
(3)There is no electron donor
(4)Oxygen is the electron acceptor

Answer: (1)

Solution

In glycolysis, oxidation of triose phosphate (glyceraldehyde 3-phosphate) reduces NAD to NADH + H, so triose phosphate is the electron (hydrogen) donor. In alcoholic fermentation pyruvic acid is decarboxylated to acetaldehyde, and acetaldehyde accepts the
