Essay about Vesicle Traffic and Cellular Transport

The cell transport process is a concept I learned in high school biology class. There are two kinds of cell transport in eukaryotic cells. Passive transport does not utilize ATP or adenosine triphosphate to displace molecules or waste. Instead, a diffusion process is used in which the material moves from a high concentration of material to a low concentration of material between the plasma membranes of the cell. The normally moving material is a small, uncharged molecule like carbon dioxide. In promoting diffusion, a transporter is used to transport charged molecules such as ions. They are embedded in the plasma membrane of the cells and help substances to enter and leave the cells and have a concentration gradient of the substances. Active transport uses ATP to transfer substances to concentration gradients. In other words, we move substances from low concentration to high concentration using ATP. As macromolecules migrate across the plasma membrane, the vesicles phagocytose molecules within the cell and release molecules from the cells. This process is called exocytosis. Endocytosis is contrary to exocytosis where cells use vesicles formed by the cytoplasmic membrane to absorb macromolecules.

But how do you know how cells transport substances, how to make vesicles, and how to fuse vesicles? The 2013 Nobel Peace Prize winners James E. Rothman, Randy W. Schekman, and Thomas C. Südhof discovered the mechanism of vesicular trafficking and how cells transport substances between other cells . Three winners were able to find the secret behind the folk traffic in three different experiments. Shekuman

Blood glucose level. Since glucose is required, the body has sufficient energy to work and insulin helps glucose enter the blood cell. As a result, the pancreas produces excessive insulin to control blood glucose levels. But the body still does not properly use insulin! Then, since the pancreas can not keep up, the blood sugar level is really high! So how do you regulate blood glucose? ! The answer depends on the discovery of vesicular transport by James E. Rothman, Randy W. Schekman, Thomas C. Südhof. Through their discovery, we can find a cure that allows glucose to enter erythrocytes without problems.

Intracellular transport science has developed rapidly in the last ten years, especially in the field of cytogenetics. Even with such major advances, many scientists are fairly complicated cellular processes that require the intracellular transport to be parts of myosin, kinesin and dynein such as dynamic cytoskeleton and molecular motor proteins It was discovered. - ... Cells, especially eukaryotic cells, are composed of various parts, called cellular organelles, where various cellular functions occur. "This localization greatly improves the efficiency of many cellular functions and prevents potentially dangerous molecules from roaming freely within the cell" (Zierath & Lendahl)

The generation of forces is essential for many different cellular functions such as vesicle transport, spindle formation, cell migration, and cell shape change. Cytoskeletal filaments and molecular motors play a major role in the forces required to produce these activities. For example, kinesin-1 and microtubules provide the necessary mechanical force for various cellular environments such as organella transport (1 ↓ -4), egg mass flow (5 ↓ - 9), process formation (5) It has been shown that 10). ⇓ ⇓ ⇓ ⇓ - 15)
