  1. Cell Membrane – Why is it so special? CELLULAR TRANSPORT – How are materials moved in and out of the cell?

  2. Plasma Membrane – Fluid Mosaic Model • Fluid Mosaic Model • Essential Biochemistry - Membrane Transport Overview

  3. PASSIVE TRANSPORT – Requires no cell energy (ATP)Uses Brownian Motion • Brownian Motion

  4. Diffusion – movement from high concen. to low concen. - requires no cell energy • Animation: How Diffusion Works

  5. 2.FACILITATED DIFFUSION – Use of carrier proteins to move materials thru a cell membrane. STILL DIFFUSION!!! • Animation: How Facilitated Diffusion Works

  6. 3. OSMOSIS – Diffusion of Water • Animation: How Osmosis Works • Iso, Hyper, Hypotonic Solutions • red blood cells • Summary of diff. cells in various solute concen.This one takes a few moments to load but it is worth it!!

  7. ACTIVE TRANSPORT – Uses cell energy (ATP) to move materials against the concentration gradient .1. Endocytosis – a. Pinocytosis – Cell Drinking b. Phagocytosis – Cell Eating c. Receptor Mediated Endocytosis2. Exocytosis • Active Transport

  8. Active Transport – Transport Proteins • Sodium - Potassium Pump

  9. Energy Conversions Autotroph – makes own organic compounds Heterotroph – utilizes other’s organic compounds • ..\Autotroph_or_Heterotroph.ppt

  10. Cell Metabolism

  11. Energy Coupling

  12. ATP Phosphorylation • ATP Phosphorylation

  13. Diffusion Demonstration
