1. Day 6

2. McGraw – Hill video of sodium potassium pump

3. 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.

4. 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.

5. 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!!!!
