AB - Abstract The mitochondria isolated from dark-grown mung bean hypocotyls oxidize succinate, l-malate, and externally added reduced nicotine adenine dinucleotide (NADH) with good respiratory control. While the pattern of respiration resembles that of animal mitochondria, there are 4 basic differences between the respiratory properties of mung bean and animal mitochondria: A) the ability to oxidize NADH, B) the pattern of succinate and malate oxidation, C) the rate of oxygen uptake, and D) the adenosine-5′-diphosphate to oxygen ratios. The apparent `Km' for malate of mung bean mitochondria is about one order higher than that expected from malic dehydrogenase in animal mitochondria, whereas the affinity for phosphate is about 5 times higher with plant mitochondria than rat-liver mitochondria. While the half-maximal stimulation of respiration by adenosine-5′-diphosphate is practically identical to that of animal mitochondria, higher concentrations of adenosine-5′-diphosphate cause some decrease in its stimulating action. 2 Present Address: Department of Botany, University of Michigan, Ann Arbor, Michigan. 1 This work was supported by a grant from the National Science Foundation.
