How much of the energy (what percentage) of oxidizing Glucose to Pyruvate is captured in Catabolism as NADH ( H ) and ATP?

40 percent.

Explanation:

About 40 percent of energy as ATP is produced due to oxidizing Glucose molecule in the process of respiration while the remaining 60 percent is lost as heat energy which is responsible for the generation of high body temperature. One molecule of glucose produces four molecules of ATP, two molecules of NADH, and two molecules of pyruvate during the first stage of respiration known as glycolysis while in the end of respiration process only ATP, carbondioxide gas and water is produced.
