What stage of cell respiration is being shown above?

The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.
Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.
Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.
