Question

Cellular respiration generates a total of 36-38 ATP molecules. How many of these come solely from glycolysis?

Answer 1

The small amount of only two.
In start start two is used... but in the later stages you get four back..
So net. is 2 ATP

Answer 2

Only 2 molecules of ATP is produced by glycolysis itself, the remaining 34/36 molecules are derived from the oxidative phosphorylation of 10 molecules of NADH(Nicotinamide Adenosine Dinucleotide + Hydrogen) and 2 molecules of Succinate.

Answer 3

You forgot that FAD (flavin adenine dinucleotide) also get reduced and is participating in the ETC.
