Question

In Redox Reaction: Pyruvate + NADH+H ---»lactate + NAD which reactants is
oxidized and which is Reduce ?​

Answer 1

Answer:

The reactants arepyruvate, NADH, and a proton. ... The process of fermentation results in the reduction ofpyruvate to form lactic acid and theoxidation of NADH to form NAD+. Electrons from NADH and a proton are used to reduce pyruvate into lactate.

Answer 2

In the redox reaction Pyruvate + NADH+H ---» lactate + NAD, Pyruvate is reduced and NADH is oxidized.

• The reactants of the given reaction are Pyruvate, NADH, and H.
• The products formed are Lactate and NAD.
• The Pyruvate is reduced to Lactate.
• The NADH is oxidized to NAD.
• In the above-given reaction, reduction and oxidation take place in the process of fermentation.
• Oxidation is the process of the removal of hydrogen or the addition of oxygen.
• Reduction is the process of the removal of oxygen and the addition of hydrogen.

Hence, in the redox reaction Pyruvate + NADH+H ---» lactate + NAD, Pyruvate is reduced and NADH is oxidized.
