<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A drug research team has synthesized a novel oral drug that acts as an agonist at multiple adrenergic receptors. When administered in animals, it has been shown to produce urinary retention at therapeutic doses with the absence of other manifestations of adrenergic stimulation. The researchers are interested in understanding signal transduction and molecular mechanisms behind the action of the novel drug. Which of the following receptors would most likely transduce signals across the plasma membrane following the administration of this novel drug?? A: GiPCRs Gi protein-coupled receptors, B: GsPCRs Gs protein-coupled receptors, C: GtPCRs Gt protein-coupled receptors, D: GoPCRs Go protein-coupled receptors, E: GqPCRs Gq protein-coupled receptors,  <response>: This is a multiple choice question asking about which receptor would most likely transduce signals across the plasma membrane following administration of a novel drug that acts as an agonist at multiple adrenergic receptors and produces urinary retention. Based on the information provided, the novel drug acts as an agonist at adrenergic receptors and causes urinary retention, which indicates alpha-1 adrenergic receptor stimulation. Alpha-1 adrenergic receptors are Gq protein-coupled receptors that signal via the Gq pathway. Therefore, the receptor that would most likely transduce signals across the plasma membrane following administration of this novel drug would be a GqPCR Gq protein-coupled receptor.E: GqPCRs Gq protein-coupled receptors
