What Molecule Donates Protons (h+) And Electrons To The Electron Transport System?

Hydrogen carriers donate high energy electrons to the electron transport chain (located on the cristae) As the electrons move through the chain they lose energy, which is transferred to the electron carriers within the chain. The electron carriers use this energy to pump hydrogen ions from the matrix and into the intermembrane space.

Good luck! As the pressure on a gas increases, the volume of that gas increases. Boyle’s law does not relate to the role of pressure as a stressor on a system. Pressure has little effect on gas.
