Endocytosis and Exocytosis

Wednesday November 14th 

#2 ATP

What form of transport would this be considered?  Active Transport (Since molecules are moving from an area of LOW concentration to HIGH concentration this would be ACTIVE transport and require energy in the form of ATP)

Give one example of this type of transport in human cells. The Sodium-Potassium Pump.  This pumps positively charged ions AGAINST their concentration gradient setting up a concentration gradient which creates an electrochemical gradient.  This allows nerve signals to be sent and aids in water balance inside of cells.

After these questions we finished up notes on active transport focusing on Endo and Exocytosis.  Below are some of the clips i showed to let you see how this works in our bodies and those of single celled organisms.
