1.A drug impairs oxyegen consumption on liver mitochondria at a buffer of 7.4pH, Mg, and adp. It inhibits O2 uptake if isocitrate, 2-ketoglutarate and malate were substrates, but it will NOT is succinate is a substrate. Where’s the site of inhibiiton: ATP synthase, malate dehydrogenase, Complex I, II, or III […]
