Question
Chapter 16, Problem 5P
Interpretation Introduction
Interpretation:
The reason for the difference in gross value and the net value of ATP formation in glycolysis needs to be explained.
Concept Introduction :
Glycolysis, also termed as the Embden-Meyerhof pathway is an oxidative pathway in which one mole of glucose is converted into two moles of pyruvate. Glycolysis occurs in the cytosol of the cells. It occurs in both aerobic and anaerobic organisms and does not include molecular oxygen.

Long explanations are NOT NEEDED. I pretty much have an idea already about this lesson, I would just like to see if my answers are correct, if it's wrong then kindly correct and just add a short explanation.
ATP accounting.
Consider 1 molecule of the sucrose (monomeric units: glucose and fructose) that will undergo complete oxidation.
a. Number of pyruvate molecules after glycolysis is 4.b. Net ATP produced in glycolysis only (via substrate-level phosphorylation) is 2.c. Number of NADH produced using the pyruvate dehydrogenase complex reaction is 1.d. Number of NADH and FADH2 produced from Krebs cycle is 12 and 4 respectively.e. Net ATP produced (complete oxidation via Malate aspartate shuttle) is 64.
