The transport of secretory proteins takes place through organelles in which of the following order?

Explanation

The transport of secretory proteins takes place through the following organelles in this order:Rough endoplasmic reticulum (RER): The RER is where secretory proteins are synthesized. The ribosomes on the RER attach to the mRNA and synthesize the protein.Golgi apparatus: The Golgi apparatus is where secretory proteins are modified and packaged. The proteins are transported to the Golgi apparatus in vesicles that bud off from the RER. In the Golgi apparatus, the proteins are modified by the addition of carbohydrates and other molecules. They are also sorted and packaged into vesicles that will be transported to the cell surface.Secretory vesicles: The secretory vesicles are the final destination for secretory proteins. They bud off from the Golgi apparatus and travel to the cell surface. When the secretory vesicles reach the cell surface, they fuse with the plasma membrane and release the proteins into the extracellular space.So, the correct order for the transport of secretory proteins is RER → Golgi apparatus → Secretory vesicles.
