No energy is used [High]  [Low] (it’s the natural flow) This means it goes down a concentration gradient.

Answer the following questions for the picture. Write the ANSWER only. 1. _________ is the movement of water. 2. _______ ________ requires energy to move.

Facilitated Diffusion and Active Transport. Facilitated Diffusion Many molecules and ions need special protein channels to pass through the cell membrane.

Facilitated Diffusion Active Transport

Chapter 3. Passive Transport  Diffusion – molecules move spontaneously (no energy used) from an area of high concentration to an area of low concentration.

Please set up your notebook for Cornell Notes. Cell membrane (plasma membrane)  Regulates the movement of materials into and out of the cell (selectively.

Types of Transport Review. The movement of particles against the direction of diffusion requiring cell energy. ACTIVE TRANSPORT.

Movement Through The Cell Membrane. How Things Move in and Out of the Cell The cell membrane is selectively permeable, allowing some substances, but not.

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

Brainstorm: How can molecules move against their concentration gradient? Need to use energy.

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.

Transport The movement of molecules and ions across a membrane.

What is the other name for the Cell Membrane? Fluid Mosaic Model

Passive Transport Does osmosis or diffusion require energy? No, molecules move along a concentration gradient.

Facilitated Diffusion Facilitated Diffusion- molecules move down a concentration gradient with the aid of special proteins.

Active Transport Requires Energy. ATP (form of energy made by mitochondria). Moves against the concentration gradient.

Endocytosis Transporting material into a cell by the in folding of a membrane.

2 Types of Endocytosis Phagocytosis- Solid particles are ingested into the cell. Pinocytosis – liquids taken into the cell.

Exocytosis Moves materials out of the cell
