What is the major difference between these two indices of the energy status of the cell: energy charge and phosphorylation potential? Ophosphorylation potential depends on the ratio of the concentration of ATP to ADP Ophosphorylation potential depends on the concentration of inorganic phosphate Ophosphorylation potential depends on the concentration of AMP Ophosphorylation potential depends on the ratio of the concentration of ADP to ATP Ophosphorylation potential depends on the ratio of the concentration of ATP to AMP
