The cell membrane transport occurs in two major ways like. 1. Passive transport. Passive diffusion. Facilitated diffusion. Osmosis. 2. Active transport.

Only a few small, relatively uncharged molecules can cross a membrane unassisted (i.e., by passive diffusion). Hydrophilic molecules that must enter or leave cells do so with help, i.e., by facilitated transport.
Nettet6. apr. 2024 · GLUT molecules tend to specialize: GLUT2, for example, delivers glucose to the digestive tract, liver, and pancreas; GLUT3 keeps the central nervous system and the brain running; GLUT4 serves the heart, muscles and fat cells. And GLUT1? It's a general transporter that can fill in where needed. NettetThis regulates the movement of molecules from one side of the membrane to the other. What is the movement of molecules from an area of high concentration to low concentration and does not require energy. Which type of movement has channels …
