While You Are Waiting What is the difference between
passive transport and active transport?
Distinguishing between
Passive Transport1. Does not require
energy input2. Movement of
materials from a high concentration to a low concentration
3. Simple diffusion, facilitated diffusion, and osmosis
Active Transport1. Requires energy
input2. Movement of
materials from a low concentration to a high concentration
3. Membrane pumps, Endocytosis, Exocytosis
Simple Diffusion
WHAT IS DIFFUSION?The movement of substances down a concentration gradient from a region of high concentration to a low concentration

today)2. Checking and going over homework3. Facilitated Diffusion Video Clip4. Facilitated diffusion pages 13 and 145. Check your answers for pages 4-6
(classwork)6. Homework: Pages 14 and 15
While You Are WaitingCells sometimes use energy in order to transport substancesacross the cell membrane. Indicate which process requires energy out of 1a or 1b and out of 2a or 2b and justify your answer.

1b
Movement of sugar molecule

2b
Check Your Homework
There are two different types of molecules14 triangles and 12 circles on the left0 triangles and 13 circles on the rightThe triangles are largerThe molecules move in all directionsBut only the circles pass through the semi-permeable membrane because they are small enough to fit through
Over an extended period of time, I would expect to see very little to no change because there is almost an equal amount of circles on either side of the membrane
Simple diffusion
Semi-permeable membrane
Check Your Homework7. The two major types of biological
molecules that compose the cell membrane are phospholipids and membrane-spanning proteins
8. There are three different types of proteins in Model 2
9. The surface proteins are on the tops of the phospholipids and the membrane-spanning proteins are next to the phospholipids
Check Your Homework10. When a carbohydrate chain is
attached to a protein it is called a glycoprotein
11. When a carbohydrate chain is attached to a phospholipid it is called a glycolipid
12. Small nonpolar or small polar molecules are shown moving across the membrane
Check Your Homework13. These molecules are passing
through the phospholipid bilayer14. There are fewer small molecules
inside the cell compared to outside the cell
15. No, the model indicates that more molecules are moving into the cell than out of the cell by the number of arrows pointing into the cell
Check Your Homework16. The small particles are diffusing across the membranes17. a. Diffusion is the net movement of molecules from an
area of (low/high) concentration to an area of (low/high) concentration.
b. The molecules will continue to move along this (semi-permeable membrane/ concentration gradient) until they reach (diffusion/equilibrium)
c. Once equilibrium is reached, molecules will continue to move across a membrane (randomly/ in one direction).
Assignment: Complete pages 13 and 14 about
Facilitated diffusion Stop at the stop sign When you are finished either start on
your homework on pages 14 and 15 or finish your multiple choice justification and turn it in
