[ (
Primary lysosomes are membrane-bound intracellular organelles that contain a variety of hydrolytic enzymes, including acid phosphatase, glucuronidase, sulfatase, ribonuclease, and collagenase. These enzymes are synthesized in the rough endoplasmic reticulum and then packaged into vesicles in the Golgi apparatus.
Primary lysosomes fuse with membrane-bound vacuoles that contain material to be digested, forming secondary lysosomes or phagolysosomes.
