2: Active Transport: 2: Active Transport Husan Bano Associate Professor Department of Physiology Al- Tibri Medical College,ISRA University ACTIVE TRANSPORT: ACTIVE TRANSPORT Definition: It is the process in which molecules move from lower to higher concentration. It is “ carrier ” and “ energy ” dependent process. ACTIVE TRANSPORT: ACTIVE TRANSPORT The substances which are actively transported are: Hydrogen ions Iron ions Urate ions Calcium ions Iodide ions Glucose and amino acids TYPES OF ACTIVE TRANSPORT: TYPES OF ACTIVE TRANSPORT Primary active transport Secondary active transport 1: Primary Active Transport :  1: Primary Active Transport Energy is derived directly from break down of ATP or other high energy phosphate. Also called “PUMP”. eg . Sodium-Potassium Pump PowerPoint Presentation: Primary Active Transport: The Na + /K + Pump Primary Active Transport (SODIUM-POTASSIUM PUMP): Primary Active Transport (SODIUM-POTASSIUM PUMP) PowerPoint Presentation: Uses ATP to move products Up a concentration gradient Secondary Active Transport: Secondary Active Transport Definition: In this process energy is derived secondarily from the ionic concentration gradient which is created by primary active transport eg Sodium-Co-transport of Glucose Sodium-Co-transport of Amino acids Sodium-potassium-2Chloride Co-transport PowerPoint Presentation: Secondary Active Transport e.g . Sodium-Glucose Symport UNIPORT , SYMPORT AND ANTIPORT: UNIPORT , SYMPORT AND ANTIPORT TRANSPORT THROUGH GATED PROTEIN CHANNELS.: TRANSPORT THROUGH GATED PROTEIN CHANNELS. Sodium (Na + ) Potassium (K + ) Calcium (Ca ++ ) Chloride ( Cl - ) ACTUAL MOLECULAR SIZE / Hydrated Size Na + 0.34nm 5.2nm K + 0.36nm 3.9nm Cl - 0.32nm 0.36nm Characteristic of protein gated channels: Characteristic of protein gated channels Have selective permeability. Can be open or close by gating system. Na + channel K + channel 5 x 3nm (size) 3 x3 nm - ve (Charge) No Out side (Gate) Inside FLOW OF POTASSIUM IONS: FLOW OF POTASSIUM IONS MODEL OF SODIUM CHANNEL: MODEL OF SODIUM CHANNEL
