How many ATP are formed by oxidation of one glucose molecule in...

In liver cells and prokaryotic cells, 38 ATP are produced by the complete oxidation of one molecule of glucose. $$\begin{aligned} \text{ Glycolysis } 2 \text{ ATP directly } & =2 \text{ ATP } \\ 2 \text{ mol. of NADH } & =6 \text{ ATP }\end{aligned}$$ Pyruvic acid to Acetyl Co-A 2 mol. of NADH = 6 ATP Citric acid 6 mol. of NADH = 18 ATP cycle $$\begin{array}{ll}2 \mathrm{ mol} . \text{ of FADH } & =4 \mathrm{ATP} \\ 2 \mathrm{ mol} . \text{ of GTP } & =2 \mathrm{ATP} \\ \text{ Total } & =38 \mathrm{ATP}\end{array}$$
