Chapter 4 Physiology of Cells. Movement through cell membranes. Substances move through cell membranes in two ways: Passive Transport: does not require any energy activity from the cell membrane Active Transport: requires expenditure of metabolic energy by the cell. PASSIVE TRANSPORT.
movement of solute particles from an area of low concentration to high
concentration and up a concentration gradient by the use of a carrier molecule
