Lysosomes are membrane-bound vesicles that contain digestive enzymes, such as glycosidases, proteases and sulfatases. Lysosomal enzymes are synthesized in the endoplasmic reticulum (ER), are transported to the Golgi apparatus, and are tagged for lysosomes by the addition of mannose-6-phosphate label. There are two types of lysosomes; secretory lysosomes and conventional ones. Conventional lysosomes are involved in the dismantling and re-cycling of various substrates presented to them through endocytocis, phagocytosis and by autophagosomes. They are responsible for returning many amino acids to the system.
