donate their high energy
the first electron acceptor molecule on the ETC. The electron then flow through a series of electron accepting molecules via repeated
reaction, releasing some energy at each step. The released energy is captured by the membrane-bound
(where the e-accepting molecules are in) and used to pump
creating a proton concentration gradient (higher outside of the cell, lower inside the cell) known as
the cell via the proton channel on the membrane, the energy is used by the enzyme
