Question

What is pyruvate? What is its role in respiration?

Answer 1

Pyruvate is a (3 carbon sugar) formed during the first stage of respiration {called glycolysis}. In glycolisis glucose (a 6-carbon sugar) is converted to pyruvate. a (3-carbon sugar)

Pyruvate formed by the glycolisis provide energy to feeds the Krebs cycle, our second step in cellular respiration.This is the role of pyruvate in cellular respiration.
