 movements across cell membranes endocytosis first the contents definition of endocytosis different types of endocytosis that is penocytosis pegocytosis receptor mediated endocytosis first the definition endocytosis endocomotel buta in in word so endocytosis is the movement of material in bulk amount from outside cell to the inside so normally this movement is in the form of vesicle a bulk of farm is a material byr's a layer lie jattain to him is called endocytosis can I think I say the diffusion say active transport say different diffusion active transport your facilitated diffusion where I may single single molecule of membrane juggie endocytosis may single molecule in bulk in large amount of molecule juggie byr's say and they're going to move kowai jattain endocytosis key teen basic types that is the penocytosis pegocytosis and receptor mediated endocytosis basically types here according to material agar material liquid form a liquid form is a material going to take you are going to that will be called as the penocytosis so pinocytosis can take a liquid material from outside of the cell to the inside or normally liquid material fluid intake is a type of soluble form a good solid material be mjooda there will be you have a radical form come in the work job o invading it k River here you see pinocytosis may fluid particles of fluid molecules jah seyi said to the (?) a vigorously unlike I'm gonna and I think like I'm not gonna malikul jahsey in every nation come on today you can tell you so okay I don't go but I don't go to that was equal to a and it is digested. Phagocytosis is basically the intake of solid material. When the cell has solid material it will also come near the solid material and the cell membrane will invaginate it and it is a vacuole form that comes into the cell. So, intake of solid material in the form of Vesical is called the Phagocytosis. Here you can see that the cell is the solid particle. Here you can see that it is a solid particle. Here you can see that it is a bacteria and it is a white blood cell. Because white blood cells usually engulf bacteria. So, as soon as the particle or bacteria comes near the cell what will the cell do? It will invert the membrane when it invaginates. As soon as it invaginates along with it it will form and when it moves inside the cytoplasm later it will fuse or merge with Lysosome. With the Lysosome both of them with the Lysosome and the solid food intake both of them it becomes Phagosome. Phagosome is absorbed by the useful material when it is taken out of the cell. Receptor mediated endocytosis In Receptor mediated endocytosis Pinosytosis and Phagocytosis the difference is that the material intake is first attached to the membrane. When it is attached to the membrane the membrane invaginates and the physical material goes inside the cell. Here you can see that the most common example is the cholesterol. When the cholesterol comes near the cell the membrane invaginates and the physical form goes inside the cell. In all types of endocytosis the material intake is always in the physical form.
