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.
From the above foods; oil, bread, steak, chicken, butter and pretzel, only 2 contain lots of carbohydrates. Colour the bread and the pretzel.
