 If all the ATP are radiolabelled in the cytosol, then predict about radioactivity of each compound.

 a) All enzyme  of glycolysis will be radiolabelled except 2-phophoglycerate and phosphenol pyruvate

 b) 2-phophoglycerate and phosphenol pyruvate are radiolabelled only the next cycle of glycolysis after cytosolic ATP radiolabelling

 c) 1,3 bisphosphoglycerate will be radiolabelled at 1 and 3 both position

 d) 2-phosphoglycerate are not radiolabelled because its enzyme phosphoglycerate mutase active site contain histidine residue exchange phosphate group from 3-phosphoglycerate

 which prediction about radiolabelling is incorrect?
