Glycolysis and pyruvate

Hey Chels194, welcome back.

1) ATP (Adenosine Triphosphate is an absolute requirement)

NAD+ (Nicotinamide adenine dinucleotide): NAD+ is involved in redox reactions, carrying electrons from one reaction to another.

2) Remeber, NAD+ is reduced to NADH. NADH is used during oxidative phosphorylation. The hydrogen of the NADH is transferred to the first molecule of the electron transport chain (FMN flavin mononucleotide in complex I.

H2O is also produced, which is used in step seven of the citric acid cyle.
 
Finally, 2 ATP molecules are also produced. These can be reused during glycolysis to extract more energy out of glucose.

bio_man, for #2, does Glucose-6-phosphate count as one? If so, what is its subsequent use? is it amino acids to make proteins? I don't think it's right. Not sure

No. G6P is not a biproduct. G6P is then rearranged into fructose 6-phosphate (F6P) by glucose phosphate isomerase. Therefore, it is technically used to create pyruvate at the end of glycolysis. It is a charged sugar molecule, not an amino acid (total different ball park chels194).

So what could be another compound for #2 to be produced?

No, I don't think so chels194. Because a single glucose molecule in glycolysis produces a total of 2 molecules of pyruvic acid, 2 molecules of ATP, 2 molecules of NADH and 2 molecules of water.
