How does glucose diffuse through a membrane

WebDec 30, 2024 · Thus the concentration of glucose stays very low, and it flows readily from the bloodstream into the cell. There are some obvious differences between transport of molecules directly through the lipid bilayer (nonmediated transport) and transport using a protein facilitator embedded in the membrane (mediated transport). WebGlucose also readily passed through the pores of the membrane. After performing Benedict’s test on the solutions, the bag’s solution as well as the beaker’s solution turned brown in color. This shows the presence of …
