The quaternary structures of the hu-man and yeast N-domains observed in the crystals are, Location of the ATP/ADP-Binding Site When ADP is lacking or when ATP is plentiful, the rate of respiration is low and is called state 4 respira­tion (Fig. 16-26). When ADP is added, the rate of oxygen consumption rises as the ADP is phosphoryla- ted. This elevated level of respiration is called state 3 respiration. Once the ADP is consumed, state 4 respi­ration is reestablished. ADP + P i + 3H + out ⇌ ATP + H 2 O + 3H + in; The formation of ATP from ADP and P i is energetically unfavorable and would normally proceed in the reverse direction.
