WebLysosomes. Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers— proteins, nucleic acids, carbohydrates, and lipids. Lysosomes … The lumen's pH (~4.5–5.0) is optimal for the enzymes involved in hydrolysis, analogous to the activity of the stomach. Besides degradation of polymers, the lysosome is involved in various cell processes, including secretion, plasma membrane repair, apoptosis, cell signaling, and energy metabolism.
