Vedclass · Answer

(A) In alcoholic fermentation,glucose is broken down into two molecules of pyruvic acid through glycolysis,producing $NADH$. In the subsequent steps,pyruvic acid is converted into acetaldehyde by the enzyme pyruvate decarboxylase. Finally,acetaldehyde acts as the terminal electron acceptor,receiving electrons from $NADH$ (via the oxidation of triose phosphate intermediates) to be reduced into ethanol by the enzyme alcohol dehydrogenase. Therefore,triose phosphate acts as the electron donor (indirectly via $NADH$) and acetaldehyde acts as the electron acceptor.
