If a small amount of atp labeled with radioactive phosphorus in the terminal position, [γ-32p]atp, is added to a yeast extract, about half of the 32p activity is found in pi within a few minutes, but the concentration of atp remains unchanged. explain. if the same experiment is carried out using atp labeled with 32p in the central position, [β-32p]atp, the 32p does not appear in pi within such a short time. why?

blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. as the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated.
