2.4.4: Define diffusion and osmosis

In active transport, energy is used to move a solute against its concentration gradient. For each molecule of ATP used, 2 K + are pumped into the cell.

ACTIVE TRANSPORT. Moving substances against their concentration gradient Cost energy!!! Types of Active Transport  Sodium-potassium pumps  Endocytosis.

Cell Theory O Three Parts O All living things are made up of one or more cells O Cells are the basic units of structure and function O All cells arise.

McGraw – Hill video of sodium potassium pump

Sodium-potassium Pump Sodium ions inside the cell bind to the carrier protein. ATP is transfers energy to the protein. The protein changes shape and releases the sodium ions outside the cell membrane. Outside the cell potassium ions bind to the pump. The pump returns to its original shape and releases the potassium ions inside the cell membrane.

Sodium-potassium Pump This pump prevents sodium ions from building up in the cell. Osmosis results when sodium levels are high The concentration gradients of sodium and potassium ions also help transport other substances, such as glucose across the cell membrane.

Activity Watch the video again and use the template provided by to explain the sodium (Na+) potassium (K) pump. You must label all parts and thoroughly explain how these process occurs using scientific vocabulary you have learned. (ion, phospholipid bilayer, channel protein, carrier protein, cytoplasm, solute pumping, active transport) IT MUST BE IN YOUR OWN WORDS!!!!
