In this lesson we discussed about the Lysosome, Endoplasmic Reticulum, Ribosome and Golgi apparatus. These four are the most important cell organelles and also very important for our ssc and other exams. We covered all important exam orientated points. Please watch the lesson and rate, review and share comment also if you have any doubt so please comment. Thanks 🙂

  7. What is in Lesson: * Lysosome Endoplasmic Reticulum (Rough And Smooth) . Ribosome * Golgi Apparatus


  8. Lysosomes: Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells. Lysosomes are known to contain more than 60 different enzymes, and have more than 50 membrane proteins. They are spherical vesicles that contain hydrolytic enzymes that can brealk down many kinds of biomolecules or we can say the digestion of macromolecules, old cell parts, and microorganisms. The lysosomes also act as the waste disposal system of the cell by digesting unwanted materials in the cytoplasm, both from outside the cell and obsolete components inside the cell. .


  9. Lysosomes: It is also called the graveyard of cell or the suicidal bag of the cell in case of hunger the cell start killing to themselves to provide the energy, in this case a normal cell may be convert into cancer cell. Lysosomes were discovered by the Belgian cytologist Christian Ren de Duve in the 1950s. * De Duve was awarded a share of the 1974 Nobel Prize for Physiology or Medicine for his discovery of lysosomes. .


  10. Endoplasmic Reticulum: Endoplasmic Reticulum is a type of organelle found in eukaryotic cells that forms an interconnected network of flattened, membrane-enclosed sacs or tube-like structures known as cisternae. The endoplasmic reticulum occurs in most types of eukaryotic cells, but is absent from red blood cells and spermatozoa. . . It serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins


  11. Endoplasmic Reticulum: The smooth ER is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane. In certain cell types, smooth ER plays an important role in the synthesis of steroid hormones from cholesterol . In cells of the liver, it contributes to the detoxification of drugs and harmful chemicals. .


  12. Ribosome: o On the basis of sedimentation coefficient it can be divided in two different types: 70S (50S & 30S): prokaryotic cell, mitochondria, chloroplast 80S (60S & 40S): Eukaryotic Cell .


  13. Golgi Apparatus: We can say it is a major collection and dispatch station of protein products received from the endoplasmic reticulum (ER) In this respect, the Golgi can be thought of as similar to a post office: it packages and labels items which it then sends to different parts of the cell or to the extracellular space. The Golgi apparatus is also involved in lipid transport and lysosome formation.
