Suicidal Bags of Cell

A cell is a basic unit and the building block of a living organism. These are the smallest units of life. There are unicellular as well as multicellular organisms in the world. Cells are responsible for energy production in our bodies. Every cell organelle carries out a special function for our body. Lysosomes are the cell organelles that are known as the suicidal bags of cells.

Types Of Cells In The Human Body

There are four main types of cells in the human body, as listed below.

Epithelial Cells: Our skin is made up of epithelial cells. Different organs in our body are made up of different epithelial cells. They cover our interior hollow organs like the oesophagus, blood vessels, stomach, etc. These cells protect our bodies and organs from external shocks.

Nerve Cells: These cells are very important for communication. They provide a channel between our brain and the different organ systems. They play an important role in our body function. They receive and transmit the sensory information from our brain and send it to the designated part of the body like muscles, eyes, ears.

Muscle Cells: They are specialized cells mainly responsible for contraction and expansion purposes. Without these cells, a person can't do a single movement. There are three types of muscle cells in the body, and they all function together. These also form a protective cover in organs and protect them from shock and internal injury. The contraction and expansion control the diameter of the hollow organ.

Connective Tissue Cells: They provide structural strength to the body and also defend from foreign invaders. Fibroblasts and fat cells two are native to the connective tissues. Other cells migrate through bloodstreams through these connective tissues.

Cells consist of cytoplasm, and a membrane encloses them. This cytoplasm contains different cell organelles like mitochondria, vacuoles, centrioles, chloroplast, ribosomes, endoplasmic reticulum, and many more things. People often wonder what suicidal bags are. To answer the question of what is the suicidal bag, we can say that lysosome is called the suicidal bag.

The lysosomes are usually found in animal cells but rare in plant cells. Ribosomes are of two types: the 70s found in prokaryotes and the 80s found in eukaryotes. Ribosomes are the structure that is important for protein synthesis. Robert Hooke first discovered the cell. Most plant and animal cells are visible only in a light microscope, and their size also varies from 1 to 100 micrometres. 

What Are Suicidal Bags Of Cells?

To answer what are suicidal bags of cell we can say that a suicide bag is called an exit bag or hood. This is used to exit some functions. Lysosomes are called suicidal bags of cells that contain different enzymes called lysosomes useful for digestion purposes. Found in cells and organelles, which are involved mainly in digestion purposes.

Material that is present outside is taken up by endocytosis, and material that is present outside is digested through autophagy. Their size varies greatly, and the larger one is ten times more than in size compared to the smaller one.

Belgian biologist Christian de Duve discovered an organelle and made clear the question that in every scientist's mind, what are suicidal bags. Lysosome sizes are from 0.1 micrometres to 1.2 micrometres. The range of pH is approx 4.5 - 5.0. The interior content is slightly acidic compared to the cytosol, which is a little bit basic.

Lysosomes are spherical or sometimes irregular in shape and membrane-bound structures. These are generated from the Golgi apparatus. They function as a recycling system of the cell because they contain hydrolytic enzymes.

These contain more than 60 different enzymes and more than 50 different membrane proteins in the cell. Enzymes of these lysosomes are synthesized in the rough endoplasmic reticulum. Then these enzymes are transferred to lysosomes from the Golgi apparatus by forming a small vesicle-like structure. Enzymes with mannose-6- phosphate tagging are specially for lysosomes.

Functions Of The Suicidal Bag

Before going into the function part, first, we have to understand what a suicidal bag is. Well, lysosomes are regarded as the primary organ for this function. They contain a variety of enzymes that are mainly for the digestion purpose of biomolecules. It involves nucleic acid, lipids, carbohydrates engulfment for digestion purposes. But to perform, these enzymes require an acidic environment. In addition to that, they are also helpful in the phagocytosis process. They integrate with different structures like phagosomes for the digestion of large structures for cellular digestion. Also helps in the digestion of foreign material, bacteria, and viruses. They are helpful in autophagy. They even can break down different materials with the help of this.

What Are Suicidal Bags Of Cells Found In The Body?

To answer the question of what are suicidal bags of cells, we can say that lysosomes are the main organelle. It is mainly of 4 types.

• Primary lysosomes: They are newly formed lysosomes from the Golgi complex. They are very small in size and contain hydrolytic enzymes in the form of small vacuoles. They are not fully functional to become the functional need to fuse it with endosomes.

• Secondary lysosomes: these are hetero phagosomes or also called digestive vacuoles. Formation of this takes place after the fusion of lysosomes with phagosomes. Then this complex helps in the digestion process.

• Residual lysosomes or tertiary lysosomes: These types of lysosomes contain residual wastes. Normally they fuse with the plasma membrane to throw all remains and debris out of the cell. This process of throwing out debris outside the cell is called exocytosis. Sometimes due to failure of this function, residues remain inside the body, and this causes different malfunctions. This leads to different diseases like hepatitis, poly-nephritis, hurler's disease, and many more different disorders.

• Autophagic lysosomes: formation of these lysosomes occurs when primary lysosomes cover the worn-out cells in the body. It helps in the disposal of cell debris. Besides all these removals of cell debris, worn cells, tissues, these are also helpful in removing an internal obstruction from the body.

So, we can conclude that its main function is intracellular digestion, extracellular digestion, autophagy, mobilization of reserves, removal of obstructions, and help in defence purposes.

The main problem or disease in this is genetically inherent deficiencies called LSD (lysosomal storage deficiency). This is an inborn error in metabolism and mainly causes due to dysfunction of lysosome enzymes. These are very rare cases, and many are due to deficiency of an enzyme, acid hydrolase. Other dysfunctions of lysosomes are also causing this.
