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

UP CPMTUP CPMT 2005

Solution:

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