Answer:
This is refers to the sequence of events which occurs during chemiosmosis for ATPs Synthesis.
1. the released during electron transport along the cytochrome carries. as proton motive force(PMF), is used to move H+ into the intramembrane space from the matrix, The accumulation of high -energy protons creates an H gradient (electochemical gradients )between the Intramembrane space and the mitochrondrial matrix.
The elctrochemical gradients produced from the Proton accumulation produced energy for the influx of H+ back into the matrix, and this energy (produced from the gradient) is used by ATPase synthase to synthesis ATPs from ADP and Pi.
