What leads to the degradation of the contents of late endosomes by lysosomal enzymes?

It forms with fragments of the "early endosomes" or migration endosomes, near the Golgi apparatus, it has a more central location within the cell and a slightly more acidic pH than the "early endosome". The latter will allow it to facilitate the function of the hydrolytic enzymes it receives from the Golgi apparatus, thus finally forming the lysosomes, organelles specialized in degradation.

In transport through "transcytosis", the endocited material is transported in endosomes from one end of the cell to the other, being released by the process called exocytosis.

Explanation:

Endosomes are not considered cellular organelles by many authors, but compartments within the cytoplasm that function as transporters of material in animal and fungal cells delimited by a simple clathrin membrane, mediated by a receptor in the extracellular domain at the starting site invagination; but recent literature does classify them as structures with sufficient characteristics to be considered organelles. They are defined as membranous organelles and most of the material they transport is transferred to lysosomes for degradation.
