Abstract
Summary In intact liver slices and liver homogenates ∼ 85% of the 25°C, g=2.004 EPR signal is now identified as stabilized mitochondrial ubisemiquinone radicals. Redox poised liver slices and liver homogenates demonstrate ubisemiquinone stability constants of 1.6×10−3 and 2.2×10−3 respectively. Such high ubisemiquinone concentrations in liver demonstrate the physiologic feasibility of “Q cycle” mechanisms for mitochondrial electron transport.
