1 Active vs. Passive Transport FA Learning Goal: Compare and contrast active and passive transport.

2 Which of the following is a type of active transport? a. Diffusion b. Osmosis c. Facilitated diffusion d. Sodium/Potassium Protein pump studyblue.com alenaimp.blogspot.com AQUAPORINAQUAPORIN

3 What is the movement of a substance from high concentration to low concentration? a. diffusion b. endocytosis c. active transport d. phagocytosis

4 Which of the following terms describes a cell releasing a large amount of particles from the cell? A. Endocytosis B. Exocytosis emimat.weebly.com http://www.dynamicscience.com.au/te ster/solutions/biology/cell/cellcytoskltn. htm

5 Which of the following statements best describes facilitated diffusion? A. Movement of a water up its concentration gradient B. Using energy (ATP) to move a solute down its concentration gradient C. Moving a solute down its concentration gradient through a protein channel D. Moving a solute down its concentration gradient through the phospholipid bilayer.

6 Active transport occurs when molecules a. Move across the cell membrane against (up) the concentration gradient b. Move across the cell membrane with (down) the concentration gradient c. Move by osmosis d. Move without using cellular energy

7 How is passive transport different from active transport? a. Active transport moves substances from high to low concentration. b. Passive transport moves substances from low to high concentration. c. Passive transport does not require ATP (cellular energy). d. Active transport does not require ATP (cellular energy).

8 Which of the following is an example of passive transport? a. Oxygen diffusing across the cell membrane along its concentration gradient b. Moving large amounts of food into a cell c. The movement sodium ions across the cell membrane using a protein pump d. A transport vesicle fusing with the cell membrane to release a large amount of particles http://www.dynamicscience.com.au/tester/solutions/biology/cell/cellcytoskltn.ht m

9 Exit Slip –Level 4 Describe a situation in which a cell would use active transport instead of passive. (2 points)
