the electrochemical potential gradient across the tonoplast for h+ ( delta mu h+ = -11.6 to -18.0 kj/mol ) was nearly equal to the free energy release from the hydrolysis of ppi in cytoplasm ( delta gpp = -18.9 kj/mol ) , indicating that the h+-translocating inorganic pyrophosphatase can work as a h+ pump in c. corallina .
