a The endocytic pathway of mammalian cells consists of distinct membrane compartments which internalize molecules from the plasma membrane and recycle them back to the surface as in early endosomes and recycling endosomes or sort them to degradation as in late endosomes and lysosomes The principal components of the endocytic pathway are Early endosomes are the first compartment of the endocytic pathway Early endosomes are often located in the periphery of the cell and receive most types of vesicles coming from the cell surface They have a characteristic tubulovesicular structure vesicles up to 1 m in diameter with connected tubules of approx 50 nm diameter and a mildly acid pH They are principally sorting organelles where many endocytosed ligands dissociate from their receptors in the acid pH of the compartment and from which many of the receptors recycle to the cell surface via tubules It is also the site of sorting into transcytotic pathway to later compartments like late endosomes or lysosomes via transvesicular compartments like multivesicular    See Answer
