Carbon monoxide effect on cytochrome c oxidase activity. COX activity determinations were performed at 550 nm, for 1 minute at 25°C, after a treatment with 10 μM of CO at 37°C for 5, 10, 15 and 30 minutes. For each sample, COX activity was determined and expressed in mU/mL. All values are mean ± SD, n = 3; * p < 0.05 compared to control mitochondria.
