Question

Imagine that you found a cell that releases many proteins into the bloodstream. What organelles/structures might be especially active in the cell? Explain in sequence what each of these organelles/structures be doing up until the release of these proteins.

Answer 1

The organelles in a cell that are involved in production and release of protein into the bloodstream are:

nucleus

ribosomes

Rough endoplasmic reticulum

Golgi apparatus

Secretory vesicles

The nucleus carries the blueprint for the synthesis of proteins.

The ribosomes are the protein forming factories of the cell.

The rough endoplasmic reticulum is responsible for synthesis of proteins for export out of the cell.

The golgi apparatus is responsible for protein modification and its export.

Secretory vesicles export the protein out of the cell through exocytosis.
