Examination shows protrusion of the eyeball when looking forward. A bruit is heard over the anterior neck on auscultation. Serum studies show autoantibodies to the thyroid-stimulating hormone receptor. The patient decides to undergo definitive treatment for her condition with a radioactive tracer. The success of this treatment directly depends on the activity of which of the following?? A: Transmembrane carrier, B: Lysosomal protease, C: Hormone-activating enzyme, D: Binding globulin, E: Anion-oxidizing enzyme,  <response>: This is a clinical vignette describing a patient with symptoms of tremor, diarrhea, weight loss, tachycardia, exophthalmos, and a thyroid bruit. She has antibodies against the TSH receptor, indicating Graves disease. The treatment described is radioactive iodine ablation of the thyroid. The success of this treatment depends on the ability of the thyroid follicular cells to take up radioactive iodine. This uptake is mediated by a transmembrane sodium-iodide symporter. Therefore, the correct answer is the transmembrane carrier.A: Transmembrane carrier
