Protons flow down a narrow space between the stator and rotor, causing the rotor and its  attached rod to rotate. The spinning rod causes conformational changes in the stationary knob, activating three  catalytic sites in the knob where ADP and inorganic phosphate combine to make ATP. How does the inner mitochondrial membrane generate and maintain the H +  gradient that  drives ATP synthesis in the ATP synthase protein complex? Creating the H +  gradient is the function of the electron transport chain. The ETC is an energy converter that uses the exergonic flow of electrons to pump H +  across  the membrane from the mitochondrial matrix to the intermembrane space. The H +  has a tendency to diffuse down its gradient. The ATP synthase molecules are the only place that H +  can diffuse back to the matrix. The exergonic flow of H
