Question

How many ATP and $C{O}_2$ molecules are produced when one molecule of glucose is completely oxidised?

Answer 1

When one molecule of glucose is completely oxidised, 38 ATP and 4 CO${}_2$ are produced. The process of glycolysis produces 2 ATP and 2 NADH (1 NADH = 3 ATP) by substrate level of phosphorylation. 1NADH is produced by the conversion of pyruvic acid to acetyl CO-A. Kreb's cycle produces 2 GTP ( equivalent to 2 ATP), 6NADH and 2 $FAD{H}_2$ (1$FAD{H}_2$ = 2 ATP).
