GENERAL HISTOLOGY

Detailed explanation-1: -From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from the cell.

Detailed explanation-2: -Answer and Explanation: The organelle that transports proteins is called the endoplasmic reticulum, or ER. The ER is an organelle made up of sac-like membranes that are folded many times. Proteins are synthesized by ribosomes that are attached to the ER.

Detailed explanation-3: -Transport vesicles are able to move molecules between locations inside the cell. For example, transport vesicles move proteins from the rough endoplasmic reticulum to the Golgi apparatus.

Detailed explanation-4: -Proteins are sorted into the regulated secretory pathway in the trans Golgi network, where they are packaged into specialized secretory vesicles. These secretory vesicles, which are larger than other transport vesicles, store their contents until specific signals direct their fusion with the plasma membrane.
