since ( a ) km value for mgadp- ( 0.05 mm ) and creatine phosphate ( 0.5 mm ) are significantly lower than km for mgatp2- ( 0.7 mm ) and creatine ( 5.0 mm ) and ( b ) maximal rate of the reverse reaction ( creatine phosphate + adp leads to atp + creatine ) equal to 3.5 mumol times min-1 times mg-1 is essentially higher than maximal rate of the forward reaction ( 0.8 mumol times min-1 times mg-1 ) , atp synthesis from adp and creatine phosphate is kinetically preferable over the forward reaction .
