She has no history of serious illness and takes no medications. She lives in a basement apartment and uses a wood stove for heating. Her temperature is 36C 96.8F and pulse is 120min. Arterial blood gas analysis shows a carboxyhemoglobin level of 11 N 1.5. Which of the following mechanisms is the underlying cause of this patients symptoms?? A: Inhibition of mitochondrial succinate dehydrogenase, B: Inhibition of mitochondrial ATP synthase, C: Increased oxygen binding capacity, D: Inhibition of mitochondrial cytochrome c oxidase, E: Increased mitochondrial membrane permeability,  <response>: This is a medical question asking about the underlying cause of symptoms in a patient with carbon monoxide poisoning. The key details are the patients exposure to carbon monoxide from a wood stove, her nonspecific symptoms like headache and nausea, and the elevated carboxyhemoglobin level. This indicates carbon monoxide poisoning. The choices describe different mechanisms related to mitochondrial dysfunction. The correct mechanism of carbon monoxide toxicity is inhibition of cytochrome c oxidase, which is located in the mitochondrial electron transport chain. D: Inhibition of mitochondrial cytochrome c oxidase
