Question

In alcoholic fermentation

(a) Oxygen is the electron acceptor

(b) Triose phosphate is the electron donor while acetaldehyde is the electron acceptor

(c) Triose phosphate is the electron donor while pyruvic acid is the electron acceptor

(d) There is no electron donor

Answer 1

Correct option (b) Triose phosphate is the electron donor while acetaldehyde is the electron acceptor 

Explanation:

 In alcoholic fermentation, 

(a) NADH (formed during conversion of triose-3 phosphate to 3 phosphoglycerate) is oxidised to NAD+ 

(b) Electrons are accepted by acetaldehyde formed by decarboxylation of pyruvate.
