channels. Active transport is then used to restore the balance of ions ready for the net time an impulse needs to be generated. Annotate the diagram to show how a protein pump is used in the active transport of sodium and potassium ions across the plasma membrane of axons. Annotate the diagram below to show how protein channels are used in the facilitated diffusion of potassium in axons. 1.4.U3 Vesicles move materials within cells. What is a macromolecule? Give one example of a macromolecule produced in the cell.
