Write answer in between .Q:A high-throughput screen to identify new sympathomimetic compounds was developed such that a transgenic line of cells was created that contained the alpha-1 red, alpha-2 yellow, beta-1 green and beta-2 blue receptors. When each of the receptors was activated a different fluorescent protein was expressed and new compounds with different properties could be identified by the fluorescence that they induced. Compound 7583 selectively induced the expression of the blue fluorescent protein. Which of the following known sympathomimetic medications if administered would similarly result in expression of only the blue fluorescent protein?? A: Albuterol, B: Midrodrine, C: Epinephrine, D: Isoproterenol, E: Fenoldopam,  <response>: This is a question about sympathomimetic drugs and their receptor selectivity. It describes a screening assay using cells expressing different adrenergic receptors tagged with fluorescent proteins. A test compound selectively activated the beta-2 receptor tagged with blue fluorescent protein. The question asks which known sympathomimetic drug would similarly only activate the beta-2 receptor.To answer this, we need to consider the receptor selectivity of the answer choices. Albuterol is a selective beta-2 agonist and would only activate the blue fluorescent protein. Midodrine is an alpha-1 agonist. Epinephrine and isoproterenol are non-selective beta agonists that would activate beta-1 and beta-2. Fenoldopam is a selective dopamine D1 receptor agonist.A: Albuterol
