Question

What distinguishes proteins destined for regulated secretion?

CA They have special surface properties that cause them to form aggregates that are packaged into special secretory vesicles.
A. They have a series of amino acids that act as a tag that marks them for packaging into secretory vesicles.
B. They are cleaved from membrane domains in the Golgi apparatus prior to being packed into secretory vesicles.

Answer 1

Proteins destined for regulated secretion are marked with a series of amino acids that act as a tag, indicating their packaging into secretory vesicles. These vesicles then fuse with the plasma membrane, releasing the proteins outside the cell.

Step-by-step explanation:

Proteins destined for regulated secretion are distinguished by a series of amino acids that act as a tag, marking them for packaging into secretory vesicles.

These vesicles then fuse with the plasma membrane, releasing the contents outside the cell.

This tagging process ensures that these proteins are transported and secreted in a regulated manner
