MICROANATOMY

Detailed explanation-1: -The RER is associated with many roles in protein synthesis, which also include post-translational modifications, folding, and sorting. Membrane-bound ribosomes in the RER translate the mature mRNA transcript into amino acids that are attached to become polypeptides.

Detailed explanation-2: -The rough ER purpose is to produce proteins that will become part of the endomembrane system, the plasma membrane or to be secreted. The endomembrane system includes all membranes within the cell, such as the endoplasmic reticulum itself, the Golgi apparatus, lysosomes and vesicles.

Detailed explanation-3: -Proteins synthesized by the rough ER include the prominent milk protein casein, and whey proteins. These proteins are packaged into secretory vesicles or large micelles and travel through the Golgi network before fusing with the plasma membrane, releasing their contents into milk ducts.

Detailed explanation-4: -The majority of the functions of rough ER is associated with protein synthesis. The rough endoplasmic reticulum also plays a vital role in protein folding. Also ensures quality control (regarding correct protein folding). More items
