Passive & Active Transport
• Animations of Active Transport & Passive Transport Types of Cellular Transport • • Passive Transport NO energy 1. Diffusion 2. Facilitated Diffusion 3. Osmosis • • Weeee!!! high low Active Transport YES energy 1. Protein Pumps 2. Endocytosis 3. Exocytosis This is gonna be hard work!! high low
Passive Transport • • • No energy (ATP) Molecules move from high to low concentration Molecules move randomly High Low Weeee!!! high low
3 Types of Passive Transport 1. Diffusion – – – Smaller molecules High to low NO energy (ATP) 2. Facilitative Diffusion – – – Larger molecules High to low NO energy with the help of transport proteins 3. Osmosis – Diffusion of water
Passive Transport Simple Diffusion Animation 1. Diffusion – Movement of particles from an area of high concentration to an area of low concentration (High to Low) • Molecules continue to move until they are evenly spaced (equilibrium) • Molecules will still move around but stay spread out http: //bio. winona. edu/berg/Free. htm
Passive Transport 2. Facilitated Diffusion – Diffusion of specific particles through transport proteins found in the membrane – Transports larger or charged molecules (ex: Glucose) A Facilitated Diffusion (Channel Protein) B Diffusion (Lipid Bilayer) Carrier Protein
Passive Transport 3. Osmosis – Diffusion of water through a selectively permeable membrane Osmosis animation • Water moves from high to low concentrations • Water moves freely through pores • Solute (green) to large to move across
Osmotic Solutions = Affect how water moves • 3 Solutions 1. Hypertonic 2. Hypotonic 3. Isotonic
Universal Solvent = Water Solution is made up of two parts… 1. Solute – substance that is dissolved 2. Solvent – Does the dissolving Example: Ice Tea – water is the solvent and tea and sugar are the solutes + =
Hypotonic Solution The solution has a lower concentration of solutes and a higher concentration of water than inside the cell (Low solute; High water) • Water will move into cell • The cell will swell or burst • Bursting is called cytolysis Trick: Hippos love water
Hypertonic Solution The solution has a higher concentration of solutes and a lower concentration of water than inside the cell (High solute; Low water) • Water will move out of cell • The cell will shrivel or shrink Trick: Hyper like a viper
Isotonic Solution The concentration of solutes in the solution is equal to the concentration of solutes inside the cell. (equal solute, equal water) • Water will move in & out of the cell at equal rates • The cell will not change size • Cell is at equilibrium “Iso” = same
Hypotonic Isotonic Hypertonic
How Organisms Deal with Osmotic Pressure Paramecium (protist) removing excess water video Bacteria and plants have cell walls that prevent them from over-expanding. In plants the pressure exerted on the cell wall is called tugor pressure. A protist like paramecium has contractile vacuoles that collect water flowing in and pump it out to prevent them from overexpanding. Salt water fish pump salt out of their specialized gills so they do not dehydrate. Animal cells are bathed in blood. Kidneys keep the blood isotonic by remove excess salt and water.

Passive Transport Overview • NO energy required (ATP) • High to low concentrations 1. Diffusion 2. Facilitated diffusion 3. Osmosis • 3 solutions – Hypertonic, – Hypotonic – Isotonic
Active Transport • Uses energy • Actively moves molecules • Movement from an area of low concentration to an area of high concentration (Low High) This is gonna be hard work!! high low
Types of Active Transport Sodium Potassium Pumps 1. Protein Pumps • Require energy (ATP) • Example: Sodium-Potassium pumps (Active Transport using proteins) Protein changes shape to move molecules: this requires energy!
Types of Active Transport 2. Endocytosis: • Large material entering a cell • • • Endo= into Cytosis = cell Two Types – – Phagocytosis Pinocytosis This is how white blood cells eat bacteria!
Two Types of Endocytosis 1. Phagocytosis = “cell eating” – Trick: “Phago my eggo” 2. Pinocytosis: “cell drinking” – Trick: “virgin pina colada”
Types of Active Transport 3. Exocytosis – Material leaving the cell • Exo = exiting • Cytosis = cell • Cell changes shape – Requires energy – Hormones or wastes released from cell Endocytosis & Exocytosis animations
In order to make hydrochloric acid, which is required in human digestion, ATP is used to move hydrogen ions from the blood to the stomach lining. This is an example of ___. • • Active Transport Passive Transport Osmotic Potential Facilitated Diffusion
