Question

How much usable energy is extracted from one glucose molecule?

Answer 1

Exactly 32 ATP from the cell respiration cycle, krebs cycle… etc.

Answer 2

The net gain of usable energy from one molecule of glucose is 32 ATP.

Step-by-step explanation:

This is because in the beginning of glycolysis, while four ATP were created, two molecules of ATP are used to start the next cycle of glycolysis. The 32 ATP molecules is about 3000 kilojoules of energy or 686 kilocalories
