| Back | - H2 atoms collected by reduced NAD/FAD transferred to ETC in membrane of cristae, where H2 dissociates into H+ and e-, high energy e- used to form ATP via chemiosis - energy released during redox reaction where e- oxidises and reduces e- carriers while passing ETC, this energy used to pump protons accross membrane, and so helps form P+ gradient, and so ATP formed, once e- gets to end of ETC it combines with O2 and H+ to form water, so O2 is final e- acceptor and without its presence ETC cant operate |
