Question

Pancreatic cells are responsible for producing insulin, a protein that regulates glucose levels in the bloodstream. Many cell organelles are involved in the creation and transport of insulin.



Which statement BEST explains the interactions that occur between the organelles to produce insulin?

Answer 1

I can’t see the images, but the BEST explanation is this pathway:

- The nucleus transcribes the insulin gene to mRNA and the mRNA exits the nucleus.
- Ribosomes on the rough endoplasmic reticulum translate the mRNA and synthesize the insulin polypeptide into the ER lumen, where it is folded and initial modifications occur.
- Transport vesicles carry the insulin from the ER to the Golgi apparatus, where it is further processed and sorted.
- Secretory vesicles bud from the Golgi and move to the plasma membrane, then fuse with the membrane to secrete insulin by exocytosis.

So choose the answer choice whose statement describes: nucleus → mRNA → rough ER/ribosome synthesis → ER → transport vesicles → Golgi → secretory vesicles → exocytosis. If you paste the text from each option or re-upload the images, I’ll pick the letter for you.
