<unk> s provide an environment for material to be sorted before it reaches the degradative lysosome. For example, low-density lipoprotein (LDL) is taken into the cell by binding to the LDL receptor at the cell surface. Upon reaching early<unk> s, the LDL dissociates from the receptor, and the receptor can be recycled to the cell surface. The LDL remains in the<unk>  and is delivered to lysosomes for processing. LDL dissociates because of the slightly acidified environment of the early<unk> , generated by a vacuolar membrane proton pump V-ATPase. On the other hand, EGF and the EGF receptor have a pH-resistant bond that persists until it is delivered to lysosomes for their degradation. The mannose 6-phosphate receptor carries ligands from the Golgi destined for the lysosome by a similar mechanism.
