WebTo move glucose from the digestive tract, where it is located after a meal, into the body cells, where it's utilized, the glucose has to cross several cell membranes. Since glucose is water soluble while cell membranes are made of fatty material, glucose can't move across cell membranes on its own. WebThe type of transport proteins present in a cell membrane determines which substances the membrane is permeable to. CO2 molecules pass directly through phospholipids. …
