Question

If lysosomes are absent in a cell what will happen?

Answer 1

Hint: Lysosomes are membrane-bound organelles that contain digestive enzymes. Lysosomes are involved in various cellular processes. They break down excess or worn out cell components and can be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it destroy itself in a process called programmed cell death or apoptosis.

Complete answer:
Lysosomes are membrane-bound organelles found in many animal cells. They are spherical vesicles containing hydrolytic enzymes that can break down many types of biomolecules. The lysosome has a specific composition, including its membrane protein and lumenal protein. The pH of light is optimal for the enzymes involved in hydrolysis, similar to the activity of the stomach.
Lysosomes, also called suicide bags, are responsible for cell death or phagocytosis under certain conditions. But the basic function of the lysosome is to digest all the waste products of the cell. So if there is no lysosome, waste will accumulate in the cell, making it toxic. This can spread and can affect various cells. This can also cause huge damage to the body by causing diseases such as cancer.
Lysosomes have three main functions: breakdown/ digestion of macromolecules (carbohydrates, lipids, proteins, and nucleic acids), repair of the cell membrane, and reaction to foreign substances (such as bacteria, viruses, and other antigens). When cells absorb food, lysosomes release their enzymes, which break down complex molecules including sugars and proteins into usable energy for cell survival. If no food is provided, the lysosomal enzymes will digest other organelles in the cell to obtain the necessary nutrients.

Note:
Lysosomes exist in almost all eukaryotic cells that resemble animals. They are so common in animal cells because when animal cells ingest or absorb food, they need enzymes in the lysosome to digest the food and use it for energy. On the other hand, lysosomes are not common in plant cells. Lysosomes are not needed in plant cells because their cell walls are strong enough to keep out the large/foreign substances normally digested by lysosomes.
