 * Before you start to edit, go to discussion page and we can discuss as a group!!!**


 * sodium potassium pump || endocytosis ||
 * exocytosis || endocytosis ||

1.each one of us should fill out what the differences are and put our names after it. there should be four in each box for the four of us.

2. what are the two main reasons cells do active transport?

3. what is a sodium potassium pump?

Sodium potassium pump is when the cell uses stored ATP to get sodium molecules out & potassium molecules in from low to high concentration. They have to use the energy because the molecules won't want to go where there's more of their type of molecule, but it's good for the cell to build its concentration gradient.

4. how are homeostasis and active transport connected?

5. what is active transport?

6. list the three main examples of active transport and what they do.

7. what is endocytosis and exocytosis?
