Question

Which of the following identifies the function of glycolysis within the entire process of cellular respiration?

Answer 1

Pretty sure its "Breaks down glucose into two pyruvate molecules"

I have no Idea what FAD is and that one doesnt sound correct
It doesnt send it to the etc as far as I know
and ADP to ATP doesnt happen in glycolysis as far as I know

Glycolysis is one of my least favorite parts of Bio so Im not entirely sure. 

Answer 2

Answer: 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.
