To determine the products of the pyruvate oxidation reaction, let's examine the key aspects of this biological process.

Understanding Pyruvate Oxidation

Pyruvate oxidation is the step in cellular respiration where pyruvate, formed from glycolysis, is converted into acetyl CoA before entering the Krebs cycle. This reaction occurs in the mitochondria and involves the decarboxylation of pyruvate.

Products of Pyruvate Oxidation

The reaction can be summarized as follows:

• Each molecule of pyruvate (C₃H₄O₃) leads to:
  1. Loss of one carbon atom in the form of carbon dioxide (CO₂).
  2. Conversion of NAD⁺ to NADH, capturing energy in the form of high-energy electrons.
  3. Formation of acetyl CoA (C₂H₃Oₗ), which then enters the Krebs cycle.

Selection of Products

From the options given, we can identify the following as products of the pyruvate oxidation reaction:

1. NADH - Produced during the reaction.
2. CO₂ - Released as a byproduct of decarboxylation.
3. Acetyl CoA - The main product that enters the Krebs cycle.
4. NAD⁺ - This is not a product but is actually a reactant that gets reduced to NADH.

Final Identification of Products

• Correct products of pyruvate oxidation:
  • NADH
  • CO₂
  • Acetyl CoA

Incorrect Options

• Pyruvate - This is the substrate, not a product.
• ATP - Not produced directly in this reaction.
• FADH₂ - Not produced in this process.
• FAD - Not directly relevant to this reaction.
• ADP - Not directly part of pyruvate oxidation.
• DPN - Another name for NAD⁺, not a product.
• Glucose - Not produced here.
• H₂O - Not produced here.
• O₂ - Not a product of this reaction.

Thus, the final correct selections are: NADH, CO₂, Acetyl CoA.
