1 The coincidence of the values of the rate constants and activation energy (56 +/- 5 kJ/mol) for the fast phase of NADPH-dependent reduction of cytochrome P-450 with values of catalytic constants and activation energy for demethylation of tertiary amines suggests that the first electron transfer process from NADPH-cytochrome P-450 reductase to cytochrome P-450 may be the rate-limiting step.
