HINT: There is more than one!It is a form of passive transport.(5JMolecules travel with the concentration gradient.C)It is how glucotse travels across the cell membrar.e.It is how oxygen and carbon dioxide travel acrossthemembrane.E|This transport is typical for large molecules.Moving with the Concentration Gradient4. "Moving with the flow" [i.e. going with the concentration gradient) isthe direction of flow in passive transport. Show this in the diagram onright by drawing in 10 total circles (to represent molecules) . You mustdecide a certain amount to place on the left vs. the right side afterviewing the arrow indicating the direction of movement. Label thconcentration side and low concentration side.Low C o n c w l r a i wHigti ConcentrationEndocytosis and Exocytosis5.
