<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 3-year-old boy is brought to the emergency department for nausea and vomiting for 1 day. His maternal uncle had a seizure disorder and died in childhood. He appears fatigued. Respirations are 32min. Examination shows diffuse weakness in the extremities. Serum studies show a low pH, elevated lactate concentration, and normal blood glucose. A metabolic condition characterized by a defect in oxidative phosphorylation is suspected. Microscopic examination of a muscle biopsy specimen of this patient is most likely to show which of the following findings?? A: Fibrofatty replacement of normal muscle fibers, B: Muscle atrophy with perimysial inflammation, C: Intermyofibrillar accumulation of glycogen, D: Endomysial inflammation with T cell infiltration, E: Subsarcolemmal accumulation of mitochondria,  <response>: This is a question about a 3-year-old boy with symptoms of fatigue, rapid breathing, muscle weakness, and laboratory findings of acidosis and elevated lactate, which suggest a defect in cellular energy production. The patients family history of a seizure disorder and childhood death in a maternal uncle raises suspicion for a hereditary metabolic disorder. The question asks about expected microscopic findings from a muscle biopsy in this patient with suspected defective oxidative phosphorylation, which is the process by which cells derive energy from nutrients. E: Subsarcolemmal accumulation of mitochondria
