Le Châtelier's Principle correct answers the equilibrium will favor products when the concentration of products is kept low. cytochrome c correct answers a heme protein that only cycles between a ferrous and ferric state during oxidative phosphorylation. Only single electron transfers are possible. oxidative phosphorylation correct answers the process in which ATP is formed as a result of the transfer of electrons from NADH or FADH2 to O2 by a series of electron carriers. This process, w...
