<Li> Deuteride: H, D </Li> <Li> Tritide: H, T </Li> <P> Hydrogen ions drive ATP synthase in photosynthesis . This happens when hydrogen ions get pushed across the membrane creating a high concentration inside the thylakoid membrane and a low concentration in the cytoplasm . However, because of osmosis, the H will force itself out of the membrane through ATP synthase . Using their kinetic energy to escape, the protons will spin the ATP synthase which in turn will create ATP . This happens in cellular respiration as well though the concentrated membrane will instead be the inner membrane of the mitochondria . </P> <P> Hydrogen ions concentration, measured as pH, is also responsible for the acidic or basic nature of a compound . Water molecules split to form H and hydroxide anions . This process is referred to as the self - ionization of water . </P>

Where are hydrogen ions concentrated in cellular respiration
