Physical structure of lysosome
Lysosomes are small spherical or circular organelles. A large number of hydrolytic enzymes are enveloped to form lysosomes. Each lysosome is surrounded by a two-layered membrane. But the coating of Spherosome or Oleosome is multi-layered. The coating is made up of lipoproteins. Lysosomes are the largest in kidney cells. Their diameter is 0.2-0.8 millimicron. Its vacuoles are filled with fluid. Lysosome coat contains stabilizers and labilizers. Stabilizer maintains the stability of the lysosomal membrane. As a result cortisone, cholesterol, heparin etc. cannot be released. That is, the stabilizer does not allow the enzyme to leave the lysosome. Labilizer disrupts the stability of the lysosomal membrane. As a result, testosterone, progesterone, vitamin-A, vitamin-B, vitamin-K etc. can be released. That is, the labilizer allows the enzyme to escape from the lysosome.
