Why Are Lysosomes Called Suicidal Bags?:<\/strong> Lysosomes are extremely small organelles inside animal cells. These, although small, are helpful in maintaining the cell clean and healthy. Scientists refer to lysosomes as suicidal bags since they are capable of breaking or even destroying various cell components when they are required. However, why should any cell part want to kill itself?<\/span><\/p>\n

In this blog we will discuss the nature of lysosomes, their functioning and why they have acquired the epithet of being suicidal bags. We will state all in simple understandable words and bring some real-life examples with which students and novices can grasp this topic with ease.<\/span><\/p>\n

What Are Lysosomes?<\/strong><\/h2>\n

Lysosomes are small round bodies that are present in the cytoplasm of animal cells. These have special chemicals referred to as enzymes. These enzymes are very potent and can degrade numerous things, such as proteins, fats and sugars. They are capable even of breaking down old or impaired structures of the cell.<\/span><\/p>\n

The Golgi apparatus is another cell organelle that forms the lysosomes, providing assistance in the packaging and processing of things.<\/span><\/p>\n

Structure of Lysosomes<\/strong><\/h2>\n

The lysosome is like a tiny bag filled with enzymes. Let\u2019s break down its parts:<\/span><\/p>\n\n\n\n\n\n\n
Part of Lysosome<\/b><\/td>\nFunction<\/b><\/td>\n<\/tr>\n
Membrane<\/span><\/td>\nProtects the cell from the powerful enzymes inside<\/span><\/td>\n<\/tr>\n
Digestive Enzymes<\/span><\/td>\nBreak down unwanted or harmful substances<\/span><\/td>\n<\/tr>\n
Acidic Interior (pH ~5)<\/span><\/td>\nHelps the enzymes to work properly<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The membrane acts like a protective wall. It keeps the enzymes locked inside so they don\u2019t harm the healthy parts of the cell. But when needed, the enzymes are released.<\/span><\/p>\n

Functions of Lysosomes<\/strong><\/h2>\n

Lysosomes perform many important functions to keep the cell clean and healthy. Here are some of the main jobs they do:<\/span><\/p>\n

1. Breaking Down Wastes<\/strong><\/h3>\n

Lysosomes break down waste materials that the cell doesn\u2019t need anymore. These can be:<\/span><\/p>\n

    \n
  • Damaged cell parts<\/span><\/li>\n
  • Dead organelles<\/span><\/li>\n
  • Leftover food particles<\/span><\/li>\n<\/ul>\n

    2. Killing Germs<\/strong><\/h3>\n

    When germs like bacteria enter the cell, lysosomes attack and destroy them.<\/span><\/p>\n

    3. Recycling Materials<\/strong><\/h3>\n

    Sometimes, lysosomes break down old parts of the cell and reuse the useful bits. This is known as <\/span>autophagy<\/b> (self-eating).<\/span><\/p>\n

    4. Helping in Cell Death<\/strong><\/h3>\n

    If a cell is badly damaged or sick, lysosomes can help the cell die in a clean and controlled way. This is called <\/span>programmed cell death<\/b> or <\/span>apoptosis<\/b>.<\/span><\/p>\n

    Why Are They Called \u201cSuicidal Bags\u201d?<\/strong><\/h2>\n

    The term <\/span>\u201csuicidal bags\u201d<\/b> may sound scary, but it actually explains the smart way lysosomes work. Here’s why they are called that:<\/span><\/p>\n

    1. They Are Able To Destroy Their Own Cell<\/strong><\/h3>\n

    The lysosomes may rupture in case the cell is infected or seriously damaged or does not work as it should. When this occurs, all the high-powered enzymes go free in the cell. These enzymes begin to digest all the contents within the cell\u2014this dries out the cell. That is why the scientists argue that the lysosome makes the cell commit suicide.<\/span><\/p>\n

    2. Helpful Self-Destruction<\/strong><\/h3>\n

    This self-destruction is not something negative. As a matter of fact, it benefits in safeguarding the body. It prevents destruction of other cells by spreading problems from the damaged or infected cells.<\/span><\/p>\n

    3. Regulation of Cell Tissue Population<\/strong><\/h3>\n

    Lysosomes are used during development (i.e. to eliminate superfluous or unneeded cells in the formation of fingers and toes in an infant). This makes the body develop in shape.<\/span><\/p>\n

    Examples of Lysosome Actions<\/strong><\/h2>\n

    Let\u2019s understand this with a few examples:<\/span><\/p>\n

    Example 1: Infection in a Cell<\/strong><\/h3>\n

    Consider a bacterium that is harmful and enters the animal cell. Lysosome will fuse with the component of the cell where the bacterium was entrapped. It then secretes its enzymes and eats the germ. In case the infection is severe, there is a possibility of the lysosome killing the entire cell to prevent spreading the germ.<\/span><\/p>\n

    Example 2: Old Mitochondria<\/strong><\/h3>\n

    The makers of energy in the cell are mitochondria. However, they wear out or get broken with time. These old mitochondria are destroyed by the lysosomes and the components are reutilized to make new ones.<\/span><\/p>\n

    Example 3: Fingers on babies Webs<\/strong><\/h3>\n

    Fingers are sometimes fused together when the baby is in her mother womb. The Lysosomes assist in dissolving the excess cells in between the fingers and mold normal fingers.<\/span><\/p>\n

    Process of Cell Suicide\u2014Apoptosis<\/strong><\/h2>\n

    Let\u2019s look deeper into the <\/span>cell suicide<\/b> process controlled by lysosomes.<\/span><\/p>\n

    What is Apoptosis?<\/strong><\/h3>\n

    Apoptosis is a natural and controlled process where cells kill themselves for the good of the body. It is not harmful, like cell death from injury. Instead, it is planned and helpful.<\/span><\/p>\n

    Role of Lysosomes in Apoptosis<\/strong><\/h3>\n
      \n
    • Activation of Signals<\/b>: The cell receives a signal (because of DNA damage, infection, or otherwise) to die.<\/span><\/li>\n
    • Activation of Lysosomes: <\/b>The lysosomes rupture and the enzymes are sent out.<\/span><\/li>\n
    • Working of the enzymes: T<\/b>hese enzymes break down the internal components of the cell.<\/span><\/li>\n
    • Cell Degeneration: <\/b>The cells degenerate and are eliminated through the other cells.<\/span><\/li>\n
    • This is an extremely vital process in development, growth and health.<\/span><\/li>\n<\/ul>\n

      Diseases Related to Lysosomes<\/strong><\/h2>\n

      Even though lysosomes help clean the cell, if they stop working properly, they can cause diseases. These are called <\/span>Lysosomal Storage Diseases<\/b>. Here are a few:<\/span><\/p>\n\n\n\n\n\n\n
      Disease Name<\/b><\/td>\nCause<\/b><\/td>\nEffect<\/b><\/td>\n<\/tr>\n
      Tay-Sachs Disease<\/span><\/td>\nLack of enzyme to break down fatty acid<\/span><\/td>\nBrain damage, nerve problems<\/span><\/td>\n<\/tr>\n
      Gaucher\u2019s Disease<\/span><\/td>\nEnzyme missing to break down fat<\/span><\/td>\nLiver and spleen enlargement, bone pain<\/span><\/td>\n<\/tr>\n
      Pompe Disease<\/span><\/td>\nEnzyme missing to break down glycogen<\/span><\/td>\nHeart and muscle weakness<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

      These diseases show how important lysosomes are for health.<\/span><\/p>\n

      Differences Between Lysosome and Other Organelles<\/strong><\/h2>\n

      Let\u2019s see how lysosomes are different from other parts of the cell:<\/span><\/p>\n\n\n\n\n\n\n\n

      Discovery of Lysosomes<\/strong><\/h2>\n

      Lysosomes were discovered by a scientist named <\/span>Christian de Duve<\/b> in the 1950s. He found small sacs with powerful enzymes in liver cells. For his work, he received the <\/span>Nobel Prize in 1974<\/b>.<\/span><\/p>\n

      Fun Facts About Lysosomes<\/strong><\/h2>\n

      These are some cool and fast facts to keep in mind:<\/span><\/p>\n

        \n
      • The lysosomes exist in animal cells but not in plants.<\/span><\/li>\n
      • They have the ability to degrade nearly all biological substances.<\/span><\/li>\n
      • The term Lysosome derives from the Greek lysis,= meaning break down and soma,= meaning body.<\/span><\/li>\n
      • Lysosomes have the ability to degrade the food, bacteria, malfunctioning organelles and even the entire cell.<\/span><\/li>\n
      • Referring to lysosomes, sometimes the scientists will talk about the cleaning crew of the cell.<\/span><\/li>\n<\/ul>\n

        Importance of Lysosomes in the Human Body<\/strong><\/h2>\n

        Lysosomes may be small, but their job is massive. Here\u2019s why they are so important:<\/span><\/p>\n

        Protection from Infection<\/b><\/p>\n

        They destroy germs and stop the spread of infection.<\/span><\/p>\n

        Proper Cell Functioning<\/b><\/p>\n

        They remove junk and keep the cell healthy and working.<\/span><\/p>\n

        Cell Renewal<\/b><\/p>\n

        They recycle materials from old cell parts, saving energy and resources.<\/span><\/p>\n

        Safe Cell Death<\/b><\/p>\n

        They help get rid of damaged or unnecessary cells during growth or disease.<\/span><\/p>\n

        Recap: Why Are Lysosomes Called Suicidal Bags?<\/strong><\/h2>\n

        Let\u2019s quickly go over what we\u2019ve learned:<\/span><\/p>\n

          \n
        • Lysosomes contain powerful enzymes that can break down the cell from the inside.<\/span>
          \n<\/span><\/li>\n
        • When a cell is damaged or infected, lysosomes release these enzymes and cause the cell to die.<\/span>
          \n<\/span><\/li>\n
        • This process is controlled and helps in protecting the body.<\/span>
          \n<\/span><\/li>\n
        • Because they can destroy their own cell when needed, they are called <\/span>\u201csuicidal bags.\u201d<\/b>
          \n<\/b><\/li>\n
        • Though they can cause cell death, this action is helpful and important for the body.<\/span>
          \n<\/span><\/li>\n<\/ul>\n

          Conclusion<\/strong><\/h2>\n

          One of the most interesting cell parts is lysosomes. They are small cleaning gadgets that can act as destroyers when the need arises. Although this power to kill the cell has prompted their being called suicidal bags, this capability is not harmful; on the contrary it is beneficial and essential.<\/span><\/p>\n

          We would be filled with junk in our cells and infections will spread easily without lysosomes. These microscopic-sized packets of enzymes assist to shield, decontaminate, and regulate the cell life cycle. They actually form one of the most significant elements of the cell world.<\/span><\/p>\n
