<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 30-year-old woman presents to her physician for her annual checkup. She has diabetes mellitus, type 1 and takes insulin regularly. She reports no incidents of elevated or low blood sugar and that she is feeling energetic and ready to face the morning every day. Her vital signs and physical are normal. On the way home from her checkup she stops by the pharmacy and picks up her prescription of insulin. Later that night she takes a dose. What is the signaling mechanism associated with this medication?? A: Increased permeability of the cell membrane to positively charged molecules, B: Increased permeability of the cell membrane to negatively charged molecules, C: Activation of tyrosine kinase, D: Increased concentration intracellular cAMP, E: Rapid and direct upregulation of enzyme transcription,  <response>: This is a question about the mechanism of action of insulin in a patient with type 1 diabetes mellitus. The patient is described as having well-controlled diabetes and is taking her prescribed insulin. The question asks about the signaling mechanism associated with insulin.Insulin is a hormone that regulates blood glucose levels. In type 1 diabetes, there is an autoimmune destruction of the insulin-producing beta cells in the pancreas, leading to insulin deficiency. Exogenous insulin administration is required to control blood glucose. Insulin binds to the insulin receptor, which is a tyrosine kinase receptor. This leads to autophosphorylation of the receptor and phosphorylation of downstream targets. This initiates a signaling cascade that ultimately results in the cellular effects of insulin.So the correct answer should be the one that describes insulin acting through a tyrosine kinase receptor.C: Activation of tyrosine kinase
