Learning Targets “I Can...” -Describe the structure of the cell membrane. -Describe the function of protein channels and protein pumps that span the cell.

Passive and Active Transport

Cell Membrane Maintains homeostasis by regulating the movement of molecules in and out of the cell.

Cellular Transport. I. General A. Definition = molecules moving across the cell membrane B. Cell Membrane is selectively permeable (lets some things in,

Membrane Transport Pages include information on membrane transport.

The cell membrane Function : Regulates what enters and leaves the cell. Provides protection and support Selective permeability Some substances can pass.

Cell Membrane What is it? – Barrier that separates cell from external environment – Composed of two phospholipid layers Other molecules are embedded in.

Active vs. Passive Transport FA Learning Goal: Compare and contrast active and passive transport.

Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.
