Abstract
Modular kinetic analysis was used to determine the sites in plant mitochondria where charge-screening stimulates the rate of electron transfer from external NAD(P)H to oxygen. In mitochondria isolated from potato (Solanum tuberosum L.) tuber callus, stimulation of the rate of oxygen uptake was accompanied by a decrease in the steady-state reduction level of coenzyme Q, and by a small decrease in the steady-state reduction level of cytochrome c. Modular kinetic analysis around coenzyme Q revealed that stimulation of the rate was due to stimulation of quinol oxidation via the cytochrome pathway (cytochrome bc
