1.(a) ( ) Trace the course of [1,6-(C-14)-2,5-(C-13)]glucose that is first processed through glycolysisand proceeds into the TCA cycle. For the glycolysis part, use the diagram below to decide where glucoseatoms end up in pyruvate. You need to illustrate only the structures of D-glucose, labeling the atoms, andof pyruvate, labeling the origin of the atoms in glucose and the distribution of the carbon isotopes in py-ruvate. After one round of the TCA cycle where will the labeled carbons be found?HOHO-СНЬОН+ 2 NAD+от+ 2 NADH+ 2 P₁2+ 2 ATPHOOH 2 ADPCH3+ 2 H₂OGlucosePyruvate
