Question

What is the fate of pyruvate before entering into cyclic pathway

Answer 1

Answer:

When sufficient oxygen is not present in the muscle cells for further oxidation of pyruvate and NADH produced in glycolysis, NAD+ is regenerated from NADH by reduction of pyruvate to lactate.

Lactate is converted to pyruvate by the enzyme lactate dehydrogenase. ... NADH is oxidized to NAD+ during this reaction.

Answer 2

Answer:

Breakdown of Pyruvate

In order for pyruvate, the product of glycolysis, to enter the next pathway, it must undergo several changes to become acetyl Coenzyme A (acetyl CoA). Acetyl CoA is a molecule that is further converted to oxaloacetate, which enters the citric acid cycle (Krebs cycle).
