Answer: Pyruvate is reduced and NADH is oxidized.

Explanation:

Fermentation is a chemical process that involves the breakdown of carbohydrates anaerobically by the activities of microorganisms.

It is the process use in the production of foodstuffs, wine and beer. Fermentation start with enzymes activities, which breakdown sugars into lactate or two molecules of three carbon organic acid, pyruvic acid. Pyruvate is reduced to lactic acid or alcohol in the absence of oxygen and nicotinamide adenine dinuleotide+hydrogen(NADH) is oxidized . This process produces two ATP per glucose molecule.

In fermentation, pyruvate is reduced and NADH is oxidized.

FERMENTATION:

  • Fermentation is the process whereby pyruvate (a product of glycolysis) is converted to alcohol or lactic acid in the absence of oxygen.

  • Fermentation only occurs in the absence of oxygen, hence, it is an anaerobic process.

  • Fermentation, which is carried out by some Bacteria and yeast, uses the product of glycolysis (first stage of cellular respiration) as follows: pyruvate and Nicotinamide adenine diphosphate + hydrogen (NADH) as follows:

Pyruvate + NADH = lactic acid/alcohol + NAD+

  • In the above equation, pyruvate is reduced by gaining electrons to form lactic acid or alcohol while NADH is oxidized by losing electrons to form NAD+.

Therefore, in fermentation, pyruvate is reduced and NADH is oxidized.
