Complex III activity in 2 Gy-irradiated compared to sham-irradiated mitochondria.
Complex III activity was decreased significantly (11%; p≤0.05) in irradiated samples. It was measured by the reduction of cytochrome c at 550 nm in the presence or absence of antimycin (Complex III inhibitor). Four independent biological replicates were used. *p≤0.05, t-test. The error bars represent standard error (SEM).
