Photosynthesis and Cellular Respiration Name:______Web-Quest Date: ____/_____/____ Hour: ___ Directions to Start: Go to Mrs. Clark’s site at: http://www.msu.edu/~bandkau1. Using the site guide to the left, select the “Links” page. Scroll down to the section that contains the links for Photosynthesis and Cellular Respiration. Another Photosynthesis Animation http://www.stolaf.edu/people/giannini/flashanimat/metabolism/photosynthesis.swf 1. When light hits Photosystem II, what happens to the water molecule?

2. The purple blobs you see are proteins. Using your class notes and know-how, what do the two purple blobs between the green Photosystems represent?

3. At the end of the animation, the H+ (hydrogen ions) move back across the membrane to produce what high-energy molecule?

Photosynthesis Animation -indepth http://www.web.virginia.edu/gg_demo/movies/figure18_12b.html 4. Which steps of photosynthesis are light dependant?

5. What does the enzyme called ATP Synthase do in photosynthesis?

Nice Electron Transport Animation http://www2.nl.edu/jste/electron_transport_system.htm --> top animation on page 6. When the electrons move across the membrane proteins, it is causing a build up in the concentration gradient. Are the hydrogen ions moving from high concentration to low concentration, or low to high?

7. With your knowledge of membrane transport, does this movement (in #6) cost the cell energy?

8. As the hydrogen ions move back across the membrane, what is put onto ADP to make ATP? 9. The enzyme mentioned in #8 is called what?

Glycolysis Animation http://science.nhmccd.edu/biol/glylysis/glylysis.html 10. Where does glycolysis occur?

11. Is glycolysis aerobic (happens with oxygen)?

12. Draw what a glucose molecule looks like?

13. In step 1 glucose gets phosphoralated (which means a phosphate is added to it), where does this phosphate come from?

14. Using your prior knowledge, what would you say the name “Glycolysis” is referring to?

15. Four molecules of ATP are made when four ADP molecules come in, but what is taken from the two pyruvates to complete the ADP to ATP transformation?

16. What is the summary of products from glycolysis?

Cool Cellular Respiration Animation http://www.qcc.cuny.edu/BiologicalSciences/Faculty/DMeyer/respiration.html 17. Cellular Respiration starts with what step?

18. During Glycolysis a 6Carbon molecule becomes what two molecules? 19. What is this 6 carbon molecule called?

20. What are the resulting two molecules called?

21. Electron Transport Chain produces what from hydrogen and oxygen?

22. During which step of Cellular Respiration is CO2 produced?

Go back to Mrs. Clark’s Links webpage, scroll up to the Cell section towards the very top of the page...

Plant Cells http://micro.magnet.fsu.edu/cells/plantcell.html 23. What does chlorophyll enable plant cells to do?

24. What are the two basic types of plant cells?

25. Click on the “Chloroplast” heading to go to the next page. Which plant structures contain chlorophyll?

26. Draw the chloroplast’s structure: 27. What is the internal fluid of the chloroplast called?

28. How are chloroplasts similar to mitochondria?

29. What is a granum?

30. What is a photon?

31. What is the cell’s chemical energy currency called? What does its letters stand for?

32. What do scientists hypothesize about the chloroplast and mitochondria’s origin in eukaryotic cells?

33. Go back to Mrs. Clark’s Links Page and play Cell Organelle Hangman to review terms you’ve learned earlier this trimester. How well did you do as you played hangman? List the organelles you covered as you played:
