Figure 3.35 The proton-driven synthesis of ATP catalyzed by the F 1 F 0 –ATP synthase: the
Rochester–Noji–Helsinki (RoNoH) mechanism. L = low-affinity conformation of the
b-subunit of the F 1 F 0 –ATP synthase unable to bind any adenine nucleotides and thus
remaining empty; M = medium-affinity conformation binding ADP plus Pi; H = high-
affinity conformation for ATP, thus able to convert (ADP + Pi) to ATP. n H+N = the n pro-
tons in the negative side of the membrane; n H+P = the n protons in the positive side of the
membrane, where n = 8–12 is the number of the c-subunits in the F 0 portion of the F 1 F 0 –
ATP synthase. The driving force for the synthesis of three molecules of ATP by one turno-
ver of the ATP synthase is provided by the exergonic movement of 8–12 protons through
the F 0 component of the F 0 F 1 subunit from the positive (P) side to the negative (N) side of
the mitochondrial inner membrane. The high-speed AFM (atomic force microscopic)
images shown are from [85].
