Question

which one of these is the function of glycolysis?
1) the breakdown of glucose into 2 pyruvate molecules
2) the breakdown of glucose into 1 pyruvate molecule
3) the production of glucose
4) the breakdown of proteins into amino acids

Answer 1

ANSWER : 1

Glycolysis, is a metabolic pathways that occur in cytoplasm of each cell. Its main function is to convert Glucose (with 6 carbon atom) into 2 molecules of pyruvate (with 3carbon atom) along with production of ATP and NADH.

Other options -

2) the breakdown of glucose into TWO pyruvate molecule.

3) the production of glucose

Reason- The glucose is produced by either gluconeogenesis or glycogenolysis { Note - it's gylco-genolysis }

4) the breakdown of proteins into amino acids

Reason- This happens during digestion of protein
