How does sugar pass through a cell membrane

WebJan 17, 2024 · Since the cell membrane will not allow glucose to cross by diffusion, helpers are needed. The cell might notice outside fluids rushing by with free glucose molecules. The membrane proteins then grab one molecule and shift their position to … WebOct 25, 2024 · Red blood cells, for example, have a cell membrane protein with an internal channel that allows glucose to pass through it. Only glucose can pass through this channel, and it can move through in either direction. This cell membrane protein is said to facilitate, or help, the diffusion of glucose across the membrane.
