WebTransporters carry a molecule (such as glucose) from one side of the plasma membrane to the other. Receptors can bind an extracellular molecule (triangle), and this activates an intracellular process. WebApr 1, 2024 · Glucose is transported by GLUT4 (a glucose transporter protein) to the plasma membrane of a muscle cell. The hormone insulin on the outside of the cell binds to a receptor on the plasma membrane that sends a signal to increase the amount of GLUT4 on the surface of the cell.

WebJun 8, 2024 · Semipermeable membranes, also termed selectively permeable membranes or partially permeable membranes, allow certain molecules or ions to pass through by diffusion. While diffusion transports materials across membranes and within cells, osmosis transports only water across a membrane.

WebAlthough glucose can be more concentrated outside of a cell, it cannot cross the lipid bilayer via simple diffusion because it is both large and polar, and therefore, repelled by the phospholipid membrane. WebAug 20, 2024 · Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes. Through the use of ion channel proteins and carrier proteins that are embedded in the cell membrane, these substances can be transported into the cell .
