      in 10 question ,its answer must be 24 ATP molecule.If any one have its explaination, please send it to me.

        The answer is correct because 1 ATP is evolved during formation of succinate from Succinyl CoA. 1 glucose is converted into 2 pyruvate during glycolysis and then in citric acid and processed in Kreb’s cycle.
