Question

What happens to pyruvate in the presence of oxygen? It enters the mitochondrial matrix and is converted to actyl CoA. It remains in the cytosol and is converted to ethanol. It remains in the cytosol and is converted to lactate. It enters the mitochondrial matrix and combines with oxaloacetate to form citrate. g

Answer 1

Answer:In glycolysis , Oxygen + Pyruvate molecules = acetyl-CoA + CO2

Where "=" means in the presence of enzyme complex pyruvate dehydrogenase complex (PDC)

Acetyl-CoA - NADH

Pyruvate oxidation or Pyruvate decarboxylation also known as link reaction, is the conversion of pyruvate into acetyl-CoA by the enzyme complex pyruvate dehydrogenase complex

Step-by-step explanation:

A carboxyl group is trimmed off of Pyruvate and released as a molecule of carbon dioxide, leaving behind a two carbon molecule.

The two carbon molecule from above is oxidised - Acetyl group, and the electrons lost in the oxidation are picked up by NAD+ to form NADH

An acetyl group is transfered to Coenzyme A, resulting in acetyl CoA
