Question

Which of the following is the function of lysosome?
A) Autolysis
B) Aid fertilisation
C) Initiation of mitosis
D) All of the above

Answer 1

Hint: Lysosomes serve as the cell's waste disposal mechanism by digesting materials from both within and outside the cell in the cytoplasm. Endocytosis takes up material from outside the cell, whereas material from within the cell is absorbed via autophagy.

Complete Answer:
In certain animal cells, a lysosome is a membrane-enclosed organelle that is located. They are spherical vesicles containing hydrolytic enzymes which can dissolve biomolecules of several kinds. A lysosome, both by its membrane proteins and its lumenal proteins, creates a particular structure.

Now, let us find the solution from the options-
- Lysosomes are minute organelle-rich single membrane-bound in which hydrolytic enzymes assist in substance lysis.
- In fertilization, they help. The sperm emits hydrolytic enzymes from the acrosome vesicles during fertilization, and digests the ovum’s membrane. This decay causes the male nucleus to enter the ovum and there is fertilization.
- Lysosome is called autophagy because in the autophagy organelles or lysosome, dried out or damaged organelles are digested and depressants are secreted to induce cell division.

Thus, the correct answer is option (D) All of the above.

Note: Lysosome enzymes are produced in the rough endoplasmic reticulum and transported by a complex consisting of CLN6 and CLN8 proteins to the Golgi apparatus on recruitment. Enzymes are transmitted into small vesicles from the Golgi apparatus to lysosomes, which combine with wider acidic vesicles.
