Final answer:
In designing the experiment, the researchers used a. γ32P-ATP. The γ (gamma) phosphate is the third phosphate in the ATP molecule.
Step-by-step explanation:
In designing the experiment, the researchers used a. γ32P-ATP. The γ (gamma) phosphate is the third phosphate in the ATP molecule. It is primarily stored between the alpha and beta phosphates.
ATP utilizes the energy released from the coupling reactions and that energy is used to power the endergonic and exergonic reactions.
