VARIOUS TYPE OF LYSOSOMES AND FUNCTION OF LYSOSOMES

Lysosomes are of four types:-

1. Primary lysosome-These are newly pinched off vesicles from trans face of Golgi bodies. Enzymes are present in inactive form.

2. Secondary lysosomes-These are formed bye fusion of phagosome and primary lysosomes. Enzymes get activated, digestion occurs and Sajid digested food passes into cytoplasm.

3. Residual bodies- These are formed when digestion is over in secondary lysosomes. They contain only undigested food matter.

4. Autophagosome- These are formed when primary lysosomes fused with its own intracellular dead or degraded cell organelles.

PIC- VARIOUS TYPES OF LYSOSOMES

FUNCTIONS OF LYSOSOMES:-

1. The lysosomes digest the food contains of phagosome and pinosome. The lysosomes of leukocytes enable the latter to devour the foreign proteins , bacteria and viruses.
2. During the starvation the lysosomes digest the Stored food contains.
3. They digest extracellular material.
       Example- during fertilization Pounds discharge several enzymes. Which are the lysosomal enzymes that digest the limiting membranes of the ovum and for penetration path in oven for the sperms.
