Question

1Your pancreas cells make a protein called insulin. This molecule allows your body to convert the sugars you eat into the energy storage molecule called glycogen. Help one of your pancreas cells complete its very important mission by writing out the plan for how it will make insulin. Include each eukaryotic cell structure that is relevant, starting with the "blueprints" to getting the molecules delivered. Present the process in order, describing what is going on at each stop. This is not a list-- show-off what you know about how cell structures get the "cell factory

What is the correct sequence of eukaryotic cell structures involved in the production and delivery of insulin in pancreas cells?

a) Nucleus → Endoplasmic Reticulum → Golgi Apparatus → Vesicles → Cell Membrane

b) Golgi Apparatus → Nucleus → Endoplasmic Reticulum → Vesicles → Cell Membrane

c) Endoplasmic Reticulum → Nucleus → Golgi Apparatus → Cell Membrane → Vesicles

d) Nucleus → Vesicles → Golgi Apparatus → Endoplasmic Reticulum → Cell Membrane

Answer 1

The correct sequence for insulin production and delivery in pancreas cells is: Nucleus → Endoplasmic Reticulum → Golgi Apparatus → Vesicles → Cell Membrane, involving gene transcription, protein translation and modification, packaging, and exocytosis.

Step-by-step explanation:

The correct sequence of eukaryotic cell structures involved in the production and delivery of insulin in pancreas cells is: Nucleus → Endoplasmic Reticulum → Golgi Apparatus → Vesicles → Cell Membrane. First, the blueprint for insulin is housed in the DNA within the nucleus. When insulin production begins, the gene for insulin is transcribed into mRNA, which then exits the nucleus to enter the cytoplasm. Once in the cytoplasm, the mRNA reaches the rough endoplasmic reticulum (RER). Ribosomes on the RER translate the mRNA into the primary structure of the insulin protein. The insulin protein then goes through initial folding and modification in the RER. After that, the protein is transported to the Golgi apparatus in vesicles. The Golgi apparatus further modifies, packages, and tags the insulin before it is packed into secretory vesicles. The vesicles then travel to the cell membrane where they release insulin into the bloodstream via exocytosis, completing the insulin delivery process.
