Fig. 4. The influence of saturated fatty acids and carboxyatractyloside (Catr) on the oxygen uptake by winter wheat mitochondria at first (1, 2, and 3) and second (4, 5, and 6) cycles of phosphorylation. Oxidation substrate is 10 mM malate in the presence of 10 mM glutamate. M + SE, n=3-6. Graph A, 50 mkM lauric acid; B, 10 mkM palmitic acid; C, 5 mkM stearic acid; and D, 5 mkM behenic acid. Lane 1, state-3 respiration; 2, state-4 respiration before addition of fatty acid; 3, state-4 respiration after addition of fatty acid; 4, subsequent state-3 respiration after 200 mkM ADP addition; 5, subsequent state-4 respiration; and 6, subsequent state-4 respiration after addition of 1 mkM Catr.
