1 ACTIVE TRANSPORT ACROSS A MEMBRANE. Overview of Active Transport Active Transport 1. Carrier Protein 2. Endocytosis3. Exocytosis.

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.

Types of Cellular Transport  Passive Transport  Does NOT require energy cell doesn’t use energy 1.Diffusion 2.Facilitated Diffusion 3.Osmosis  Active.

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

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

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

Aim: How can we compare active and passive transport?

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.

What is the other name for the CMB? Fluid Mosaic Model

Passive Transport Does osmosis or diffusion require energy. No them move along a concentration gradient

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

Active Transport Requires Energy ATP Moves against the concentration gradient

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

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

Exocytosis Moves materials out of the cell
