Welcome to class! Please take out your Comp Books

1. Welcome to class! Please take out your Comp Books Tuesday, September 22

2. What you will learn & do today: • Do a simulation of processes that occur in the phospholipid bilayer. • Critically think about the processes that occur in the phospholipid biayer that we talked about last week- how enzymes work, etc. • Learn about active and passive transport

3. Warm-Up Question 1 To the best of your ability draw the phospholipid bilayer. (If you need help look on page 74 in your book.)

5. Warm-Up Questions 2 & 3 • Where is the phospholipid bilayer located in the cell? • How does changing temperature & pH affect the rate of enzyme-controlled reactions?

6. Phospholipid Bilayer Simulation Activity Ground Rules

7. Ground Rules • Walk directly out to the field • Respect fellow classmates’ space • No horse-playing, touching, kicking other students • Do you best!

8. How the Activity Works • Each of you will be given a placard that names a structure found in the phospholipid bilayer you will wear this around your neck. It is your job to figure out the role of the structure. • As a class we will simulate how the structures work in the cell by everyone acting out the roles on their placard. • We will do 3 simulations and the shape of the structure is going to be a circle. After each simulation is checked by Mr. Sears and Miss Michelle, students will then trade placards with another student and we will do the simulation again; changing the temperature and pH of the cells. (This should change how you act in your role. Remember your warm-up questions.)

9. Simulation Reflection Please take out your Comp Books!

10. What is the role of receptors in the phospholipid bilayer? • Why are certain reactions blocked from happening in the cell? • What happens when an enzyme successfully connects to a receptor located on the phospholipid bilayer? • What are active and passive transport? When did you see these types of transport happening in the simulation?
