Answer:
In the In the fourth step electrons from the reduced coenzymes NADH and FADH2 are passed along the Electron transport chain (ETC) to provide energy to proton pumps.
These transport proteins move H+ from the matrix to the intermembrane space across the inner mitochondrial membrane in a process known as chemoosmosis. The diffusion of H+ through the enzyme ATP synthase provides the energy to phosphorylate ADP, forming ATP. Electrons from NADH and FADH2 provide this energy to move hydrogen ions (also called protons) across the inner mitochondrial membrane via active transport. Protons move from an area of higher concentration in the mitochondrial intermembrane space to an area of lower concentration in the mitochondrial matrix by simple diffusion through a transmembrane protein called ATP synthase.
The hydrogen ions and elactrons released by the coenzymes in the electron transport chain ultimately are linked to oxygen to form water. You must be able to explain why oxygen appears in the equation for cellular respiration because the only reason organisms require atmospheric oxygen is to capture electrons at the end of the electron transport chain.
To summarize, the metabolism of one molecule of glucose results in the production of 36 ATP by anaerobic processes of substrate level phosphorylation during and 20 ATP in the citric acid cycle. The principal product of the citric acid cycle is not ATP, but instead 8 molecules of NADH and 2 molecules of FADH2 per glucose. The ETC and chemiosmosis generate approximately 32 ATP per glucose molecule, making the electron transport chain and chemiosmosis the most energy production phases of cellular respiration.
