Which of the following identifies the function of glycolysis within the entire process of cellular respiration?
breaks down glucose into two pyruvate molecules
reforms nad+ and fad to reuse in other parts of respiration
sends energy-rich molecules to electron transport chain
converts adp to atp for use as cellular energy

The correct answer is- Breaks down glucose into two pyruvate molecules.

Glycolysis is a metabolic process in which glucose is broken down into two molecules of pyruvate ( 3 carbon molecule) with the release of net 2 ATP and 2NADH molecules.

It occurs in cytoplasm the cell and it is the first phase of cellular respiration.

Glucose is one of the most significant source of energy for living organisms. Thus, through glycolysis, energy is extracted and utilized by the cell.
