For this reaction, found in typical biochemistry textbook:
$C_6H_{12}O_6 + 6O_2 \to 6CO_2 + 6H_2O$
I am interested in where do the oxygen atoms of $6O_2$ go. I think they go to $6H_2O$, but this is not sufficient for balance. So Does oxygen atom from $6CO_2$ also get into the carbon dioxide. Experimentally these can be confirmed by iostope labeling experiments. Reference to any such experiments will be appreciated.
I am interested in this question because the central metabolism can be understood as a electron transfer process where glucose is donor and oxygen is acceptor. We need to calculate, effectively how many electrons glucose transfers to oxygen in case of full oxidation.
