Question

During which stage of cellular respiration is glucose broken down into two molecules of pyruvic acid?

a.)electron transport chain b.)glycolysis
c.)Krebs cycle
d.)acetyl CoA formation

Answer 1

I took the test it's B

Answer 2

During glycolysis, glucose is metabolised into pyruvate, which is a three carbon compound. The process takes place inside cytosol. Molecular oxygen is not involved in the same, and a little energy is produced in the form of ATP molecules. Pyruvate is then oxidised to oxygen and carbon dioxide, with further production of ATP molecules.
