<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A researcher is tracing the fate of C-peptide, a product of preproinsulin cleavage. Which of the following is a true statement regarding the fate of C-peptide?? A: C-peptide is immediately degraded by the proteasome, B: C-peptide is packaged with insulin in secretory vesicles, C: C-peptide exits the cells via a protein channel, D: C-peptide is further cleaved into insulin, E: C-peptide activates an intracellular signaling cascade,  <response>: This is a question about the fate of C-peptide after it is cleaved from preproinsulin. We need to identify which statement about what happens to C-peptide after this cleavage is true.A is incorrect because C-peptide is not immediately degraded by the proteasome. B is correct because C-peptide is packaged together with insulin in secretory vesicles after cleavage from preproinsulin.C is incorrect because C-peptide does not exit cells via a protein channel, it is secreted from cells via exocytosis of secretory vesicles.D is incorrect because C-peptide is not further cleaved into insulin. It is cleaved from preproinsulin and remains as C-peptide.E is incorrect because C-peptide does not activate any intracellular signaling cascades.B: C-peptide is packaged with insulin in secretory vesicles
