Journey into the Cell: Lysosomes

Saturday December 9, 2006
Lysosomes are membranous sacs of enzymes. They are made by the endoplasmic reticulum and Golgi complex.

Lysosomes contain various hydrolytic enzymes that are capable of digesting nucleic acids, polysaccharides, fats, and proteins.

They are active in recycling the cell's organic material and in the intracellular digestion of macromolecules. In addition, in many organisms, lysosomes are involved in programmed cell death.
