Answer:
d. 36 -38
Explanation:
From the oxidation of a glucose molecule, at most 38 ATP is produced (generally between 36 and 38 ATP molecules depending on the external conditions that determine the conversion efficiency), distributed as follows: glycolysis produces eight ATP (six come from the oxidation of the two NADH, the other two form directly); the conversion of pyruvic acid into acetyl-CoA produces six ATP (from two NADH); The Krebs cycle produces 24 ATP (18 come from six NADH; four, from two FADH2; the remaining two are formed directly).
40% of the free energy produced in the oxidation of glucose is retained in the form of ATP molecules. In other words, the process has an efficiency of 40%
