Transcription

1 Name: Block: Date: Student #: Photosynthesis & Cellular Respiration Internet Activity Illuminating Photosynthesis Go to lps.org and enter the jump code P4BR into the search box in the upper right corner. Complete the following statements/fill out the applicable information. Click on the link that reads Launch Interactive. Read the introductory poem. Click on The Cycle at the top of the box. 1. Click on the following items, and explain what happens: a. The shade over the window: b. The container of water: c. The child: 2. What gas does the child provide for the plant to use? 3. What gas does the plant provide for the child to use? 4. Will the plant continue to produce this gas if the shade over the window is closed? Try it out and see! 5. 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, click on next. 6. What type of molecule is show in the leaf? 7. Draw one of the molecules below, as it is shown in the leaf.

2 8. According to the reading, these molecules do no come from the tap. From what two places do they come? Click on next and watch carefully. You may click on replay to watch this again. 9. What is stripped from each water molecule? 10. From where does the cell get the energy to do this? 11. The stripped molecules form pairs. Where does it go after this? Click on next. 12. What gas enters the leaf? 13. This gas enters through holes in the leaf. What are they called? Click on next. 14. What molecule is formed once again? Click on next. 15. Another molecule is formed ( and boy is it sweet ). Draw this molecule below as shown. 16. What is the name of this molecule?

3 Click on Thre Puzzlers at the top of the box. Answer each of the following questions, and explain in your own words (This means, do not google these questions and copy down the answers). 17. Can a tree produce enough oxygen to keep a person alive? Explain. 18. Cn a plant stay alive without light? Explain. 19. Can a plant survive without oxygen? Explain. Cell Respiration BioCoach Activity Go to lps.org and enter the jump code OLGD into the search box in the upper right corner. Complete the following statements/fill out the applicable information. 20. Cellular respiration is the process by which the chemical energy of is released and partially captured in the form of. 21.,, and can all be used as fuels in cellular respiration, but is most commonly used as an example to examine the reactions of and pathways involved. Go to: 22. We can divide cellular respiration into three metabolic processes:, the, and. Each of these occurs in a specific region of the cell. 23. occurs in the cytosol (cytoplasm). 24. The Krebs cycle takes place in the matrix of the.

4 25. via the electron transport chain is carried out on the inner mitochondrial membrane. 26. Now click the Practice Button on the top right corner of the page (in the cellular respiration overview section). Take the quiz and record the correct answers below. When you are done recording the answers below return to the original screen and click next concept. 27. In glycolysis, the 6-carbon sugar,, is broken down into two molecules of a 3- carbon molecule called. 28. The Krebs cycle occurs in the mitochondrial matrix and generates a pool of (ATP, NADH, and FADH2) from the oxidation of pyruvate, the end product of glycolysis.

5 29. The electron transport chain allows the release of the large amount of stored in reduced NAD + (NADH) and reduced FAD (FADH2). 30. In many cells, if oxygen is not present, pyruvate is metabolized in a process called. 31. The chemical energy stored in glucose generates far more ATP in than in respiration without (glycolysis and fermentation). What I Learned? 32. Define cellular respiration and name the three organic compounds that can be used as fuel in cellular respiration. 33. What are the three metabolic processes of cellular respiration? Which one of these processes releases the most chemical energy? 34. What are the raw materials needed for aerobic cellular respiration and what are the end products?
