Kinetics and Efficiency of Aerobic Phosphoryla- tion—An incubation mixture (see experimental procedure) was warmed for five minutes at 30°C (in the absence of enzyme). An aliquot was withdrawn and acidified with TCA (zero time), and the reaction was initiated by adding enzyme (26 jug of a sucrose fraction in a final incubation volume of 734 /il). Optical density at 340 m^ was followed (30°C, thermostated cuvette compartment) and at intervals aliquots were withdrawn and acidified with TCA. The su- crose gradient fraction used contained maximal succinic dehydrogenase activity (in a sucrose density gradient centrifugation of crude dark extract). All values given have been corrected for the zero time blank (0.25 m//moles/ ml). A control tube, lacking DPNH, incubated at 30°C for 12 minutes gave a value of 0.98 m//moles M-6-P/ml..
