What are lysosomes?
Lysosomes are spherical vesicles which contain hydrolytic enzymes that can break down many kinds of biomolecules.
Besides degradation of polymers, the lysosome is involved in various cell processes including secretion, plasma membrane repair, cell signalling and energy metabolism.
They also act as the waste disposal system of the cell by digesting unwanted materials in the cytoplasm, both from outside the cell and obsolete components inside the cells.
Lysosomes are capable of fusing with other organelles and digesting large structures or cellular debris, through cooperation with phagosomes.
Lysosome is a membrane bound organelle found in nearly all animal cells. They are known to contain more than 60 different enzymes. The enzymes responsible for the hydrolysis require an acidic environment for optimal activity.
