The electron transport chain forms a proton gradient across the inner mitochondrial membrane, which drives the synthesis of ATP via chemiosmosis. 29 . Therefore if the total is an odd #, the charge of the ion is 1- (phosphate is the only 3- you need to know). Chlorine has 17 electrons (a charge of -17) and 17 protons (a charge of +17), so the overall charge is zero. If the total of the group numbers of the atoms is odd, it will need an odd number of electrons to make the total even. The ions that comprise calcium phosphate are the Ca2+ calcium ion and the (PO43?) The rate and extent of electron transfer from ferrous ion to ferricytochrome c are enhanced by the presence of inorganic orthophosphate at concentrations comparable to those of reductant and oxidant.
