Contribution of each oxidative phosphorylation pathway component to the total resistance to energy transfer

	Fuel Transport/Dehydrogenases, %	Electron Transport Chain, %	ATP Production/Transport, %
G + M
Control	16.4 ± 2.2	24.5 ± 4.7	59.1 ± 5.4
Ischemia	13.4 ± 1.6	25.2 ± 4.6	61.4 ± 4.5
P + M
Control	19.0 ± 0.9	34.0 ± 7.0	47.1 ± 7.1
Ischemia	15.6 ± 5.4	28.9 ± 5.5	69.9 ± 10.5

Values are means ± SE; n = 4–6 rats per condition. Ischemia lowered the activity of every segment of the oxidative phosphorylation pathway but did not alter the percent contribution of each component of the total resistance of the pathway. G, glutamate; M, malate; P, pyruvate. *P < 0.05, significantly different from control, two-tailed t test.
