Rates of Turnover of y and 8 Phosphates of ATP If a small amount of ATP labeled with radioac- tive phosphorus in the terminal position, [y-32PJATP, is added to a yeast extract, about half of the 32p activity is found in P, within a few minutes, but the concentration of ATP remains unchanged. Explain. If the same experiment is carried out using ATP labeled with 2P in the central position, [8-2PJATP, the 2P does not appear in P; within such a short time. Why?
