By dislocation the internal of a cell, antithetic functions can be undertaken in diametrical incorporated compartments at heart the same cell.This berth allows cells to do more than one thing. Level 2 207. retrace the kindred among ribosomes, ER, the Golgi apparatus, and exocytosis. Answer Ribosomes are the sites of protein synthesis. more or less of the proteins have loss leader sequences on them, which allow them to be inserted into the cisternae of the endoplasmic reticula to which the ribosomes are attached. The proteins can travel in the endoplasmic reticulum to the Golgi apparatus, where they can be change and case for secretion. Vesicles break off from the flattened membranous sacs of the Golgi apparatus.Some of the vesicles carry proteins to the plasma membrane, where the proteins can be secreted from the cell by exocytosis.
