					CELLULAR RESPIRATION and
PHOTOSYNTHESIS WEBQUEST
DIRECTIONS: As you working through the WebQuest, click on the
links to find answers to the questions.

Part I: Function and Equation for Respiration

1. Click on the following two links and write a definition for cellular
respiration in your own words.
Miller and Levine Biology Book              Biology Coach PH

2. What living things/cells perform alcoholic fermentation? What living
things/cells perform lactic acid fermentation?

3. Write the chemical equation for cellular respiration (aerobic) identifying
the reactants and products.
Equation for Cellular Respiration

4. How does the equation for cellular respiration (aerobic) compare with the
equation for photosynthesis?
Photosynthesis: Reactants                           Products
Light Energy (sun) + 6CO2 + 6H2O                   C6H12O6 + 602

5. What is ATP? Why is it an important product of cellular respiration?
ATP

6. Using the same link you used in Question 5, write the chemical equation
for the breakdown of ATP. Does the reaction release energy
(exergonic/exothermic) or absorb energy (endergonic/endothermic)?
Support your answer.

7. Using the same link you used for Question 5, write the chemical equation
for the synthesis of ATP. Does the reaction release energy
(exergonic/exothermic) or absorb energy (endergonic/endothermic)?
Support your answer.
Part II: Main Site of Cellular Respiration
Respiration organelle
8. What is the main site of cellular respiration in the cell?
9. Make a sketch of the respiration organelle and label the parts.
10. What energy molecules are produced in this respiration organelle?


Part III: Aerobic and Anaerobic are Two Types of Cellular Respiration
Use a search engine (like google) to answer these questions.
11. What is the difference between aerobic and anaerobic cellular
respiration?

12. What is lactic acid fermentation? Where does it occur?

13. What does a build up of lactic acid cause?
14. What is alcoholic fermentation?
15. In what industry is alcoholic fermentation important?
16. Which produces the larger amount of energy – aerobic or anaerobic
respiration? Support your answer with information from your research.

17. Write a summary of cellular respiration. In your response:
    State the function of cellular respiration
    Identify the site of cellular respiration
    Compare aerobic and anaerobic forms of cellular respiration
   
Part IV: Illuminating Photosynthesis

    Got to/ type in the following link:
     http://www.pbs.org/wgbh/nova/methuselah/photosynthesis.html#
    Read the introduction entitled “Illuminating Photosynthesis” by Rick Groleau.
    Click on the link that reads: “Go to Illuminating Photosynthesis.” Read the
     introductory poem.
 Click on “The Cycle” at the top of the box
1. Click on each of the following items, and explain what happens:
   a. The shade over the window:
   b. The container of water:
   c. The child:

2. a. What gas does the child provide for the plant to use?
    b. What gas does the plant provide for the child to use?
    c. Will the plant continue to produce this gas if the shade over the window is
    closed? (try it out to see!)

3. According to this animation, what 3 main things does the plant need for
   photosynthesis to occur?

 Click on “The Atomic Shuffle” at the top of the box.

 Read the introductory poem, and click on “next”
4. What type of molecule is shown in the leaf?

5. Draw one of the molecules, as it is shown in the leaf.

6. According to the reading, these molecules “do not come from the tap.” What two
   places do they come from?

 Click on “next” and watch carefully. You may click on “replay” to watch this
   again.

7. a. What is “stripped” from each water molecule?
   b. From where does the cell get the energy to do this?
   c. The stripped molecules form pairs. Where does it go after this?

 Click on “next”
8. a. What gas enters the leaf?
   b. This gas enters through “holes” in the leaf. What are they called?

 Click on “next”
9. What molecule is formed once again?
 Click on “next”
10. Another molecule is formed (“and boy is it sweet”). Draw this molecule as
    shown.
  11. What is the name of this molecule?

   Click on “Three Puzzlers” at the top of the box.
  12. Answer each of the following questions, and explain in your own words.
  a. Can a tree produce enough oxygen to keep a person alive? Explain.
  b. Can a plant stay alive without light?
  c. Can a plant survive without oxygen? Explain.

  Part V: RAGS TO RICHES

  Click on the following link to play the Rags to Riches Game (Like Who Wants to be
  a Millionaire?)
  http://www.quia.com/rr/34827.html?AP_rand=740121695
  (Click on play game, you do not need a log in name and password.)

  Play as many times as possible until you win (or get as high as possible) and write
  down 10 different questions and CORRECT answers that you encounter throughout
  the game on the back of your answer sheet.
