Different transport mechanisms in a cell
WebThe cell membrane consists mainly of phospholipids and proteins in the form of a lipid bilayer. Mechanisms for moving chemicals through the cell membrane include: passive diffusion, facilitated diffusion, active transport, and endocytosis. Factors such as human anatomy and chemical structures affect the movement of chemicals in the body. NGSS WebMay 4, 2024 · The phospholipid bilayer, the basic structural unit of biomembranes, is essentially impermeable to most water-soluble molecules, ions, and water itself. In order to support its’ activities, a cell must bring in nutrients from the external environment across the cell membrane. In bacteria and archaea, several different transport mechanisms exist.

WebThree types of Endocytosis. phagocytosis, pinocytosis, and receptor-mediated endocytosis. Phagocytosis. "cell-eating", engulfing large particles such as bacteria, only a few specific types of cells do this. Pinocytosis. "cell-drinking", taking in droplets of fluid from outside cell, droplets contain molecules that can be used in the cell. Web(This transport of sodium sets up the nerve cell for the impulse that will occur within it later.) Endocytosis and exocytosis. The final mechanism for movement across the plasma membrane into the cell is endocytosis, a process in which a small patch of plasma membrane encloses particles or tiny volumes of fluid that are at or near the cell ...
WebI thought the process was: (1) some extracellular substance, say a protein, binds with a receptor on the cell's membrane. (2) the cell membrane invaginates and "reaches" around the protein, enveloping it. (3) the cell membrane, having surrounded the protein, pinches off, creating an intracellular vesicle containing the protein.
