What happen when electrons are passed down the electrons transport chain?
Hydrogen ions are pumped across the mitochondria's inner membrane producing a concentration gradient
What is the role of hydrogen ion gradient used for in cellular respiration in the mitochondria?
The hydrogen ion gradient is used to drive ATP synthesis. 32 to 34 molecules of ATP are produced. The hydrogen ion gradient is the result of NADH in the electron transport system of the mitochondria.
What ions accumulate in the outer compartment of the mitochondria during electron transport phosphorylation?
Hydrogen ions
What forces hydrogen ions to flow through the F0 subunit?
a concentration gradient
What will most likely happen if a toxin causes the hydrogen ion pump to stop moving H ions outside the mitochondrial membranes of the bird's cells?
Then there will be no build up of protons in the outer lumpen of the mitochondria. Without a heavy concentration of hydrogen ions ( protons ) there there will be no moment of hydrogen ions down their concentration gradient through the ATPase pump and no ATP generated.

Why mitochondrion is called powerhouse of the cell?
Mitochondria are the powerhouses of cells because they are the epicenter of the electron transport chain. While glycolysis can occur in the cytoplasm, the bulk of energy production takes place due to a hydrogen concentration gradient found in the mitochondria.
Why are parietal cells acidophilic?
Parietal cells are acidophilic because they contain a large number of mitochondria. The mitochondria, which are needed to pump hydrogen ions against their concentration gradient, are acidophilic; therefore, parietal cells are acidophilic as well.
In what organelle does the electron transport chain function?
The electron transport chain converts energy stored in hydrogen ions and various other substances formed in early cellular respiration to produce high energy ATP in mitochondria. Mitochondria contain both an inner and an outer membrane, and it is along the inner membrane that the actual reactions of the chain occur. Inside the inner membrane a surplus of hydrogen ions is created that produces a concentration gradient across the membrane to the intermembrane space. This gradient causes a force that pushes hydrogen ions out of the innermost matrix and into the intermembrane space. This exchange occurs through special proteins called ATP synthase that convert low energy ADP into high energy ATP whenever a hydrogen ion is sent through one. When all is said and done, the excess electrons and hydrogen are bonded to oxygen to form water molecules.

a concentration gradient
What drives the ATP synthase reactions that produced ATP?
The proton gradient produced by the electron transport chain powers ATP production. This process is called chemiosmosis, in which H+ ions from the thylakoid space (in mitochondria they are in the intermembrane space) pass through ATP synthase to areas of lower concentration (in chloroplasts, the stroma, and in mitochondria, the mitochondrial matrix). As they pass through ATP synthase, the catalytic knob of the ATP synthase is turned. The turning of this knob (which is powered by diffusion of H+ ions) powers the anabolic production of ATP.

Then there will be no build up of protons in the outer lumpen of the mitochondria. Without a heavy concentration of hydrogen ions ( protons ) there there will be no moment of hydrogen ions down their concentration gradient through the ATPase pump and no ATP generated.
