Watch the Bozeman videos entitled "The Cell Membrane" and "Transport Across the Membrane" and answer the following questions.
1. What is the name of the model that explains how cell membranes work? Explain its name.
2. What are the different types of molecules that can be found within a cell membrane?
3. Why can O2 and CO2 move through the cell on their own but H2O (water) cannot?
4. Question for thought: Why is it that we need to use detergent to extract the DNA of a cell?
5. What are the two forms of transport across the cell membrane?
6. What are the 3 types of passive transport?
7. What are the two types of active transport?
8. Where does diffusion take place in our body? How does it work?
9. What happened in the "U tube" experiment? What type of transport was shown in this experiment?
10. Why is facilitated diffusion a form of passive transport even though it involves a transmembrane protein?
11. What is a concentration gradient?
12. what does active transport require in order to take place?
