Question

How many ATP molecules released when 1 molecules of glucose is oxidised in our liver cells?

• A. 36
• B. 38
• C. 2
• D. 8

Answer 1

Answer: (B)

In liver cells and prokaryotic cells, $38ATP$ are produced by the complete oxidation o f one molecule of glucose.
$\begin{array}{ccc}\text{Glycolysis}& 2ATP\text{directly}& =2ATP\\ & 2\text{mole of }NADH& =6ATP\\ \text{Pyruvic acid to}& & \\ \text{acetyl}CoA& 2\text{mol of}NaDH& =6ATP\\ \text{Citric acid cycle}& 6\text{mol of}NaDH& =18ATP\\ & 2\text{mol of}FADH& =4ATP\\ & 2\text{mol of}GTP& =2ATP\\ & \text{Total}& =38ATP\end{array}$
