What are Lysosomes?

Friday November 7, 2008
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 acid, 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.
