Presentation Transcript

  1. Cellular Energy

  2. What do you call an organism that can make its own food? • autotroph

  3. What kind of organism has no chloroplasts in its cells? (Has to eat other organisms for energy) • heterotroph

  4. Why do we breathe in oxygen? • So our cells can do cellular respiration

  5. Where does the carbon dioxide we breathe out come from? • Cellular respiration in our cells produces carbon dioxide as waste.

  6. What is the relationship between cellular respiration and photosynthesis? • They are opposites. The products of one are the reactants of the other

  7. What is the term that means without oxygen? • anaerobic

  8. What kind of cellular respiration is anaerobic (uses no oxygen?) • fermentation

  9. What are the two types of fermentation? • Lactic acid fermentation and alcoholic fermentation

  10. Which kind of fermentation makes your muscles sore? • Lactic acid fermentation

  11. Which kind of fermentation is used in breadmaking, and to make beer and wine? • Alcoholic fermentation

  12. Which kind of cellular respiration will your cells use if you are doing aerobic exercise – fermentation, or the three step process in the mitochondria? • mitochondria

  13. Which kind of respiration produces more ATP’s – fermentation or the kind that uses oxygen? • Cellular respiration with oxygen (in mitochondria) produces much more energy (ATP’s)

  14. How many ATP’s does cellular respiration produce in total? • 38 ATP’s

  15. What is the process of capturing light and converting it to sugars called? • photosynthesis

  16. In what cell organelle does photosynthesis happen? • chloroplast

  17. What is the first phase of photosynthesis called? • Light dependent reaction

  18. What is needed for the light dependent reaction? • Water& sunlight

  19. What pigment captures the light energy in the chloroplast? • chlorophyll

  20. In what part of the chloroplast does the light dependent reaction occur? • thylakoids

  21. What do you call a stack of thylakoids? • A granum (multiple grana)

  22. What does the light dependent phase (first phase) of photosynthesis produce? • Small amount of ATP to power second phase, oxygen, NADPH for phase 2

  23. What is phase 2 of photosynthesis called? • Calvin cycle, or light independent reaction

  24. In what part of the chloroplast does the light independent reaction (Calvin cycle) occur? • stroma

  25. What is needed for the Calvin cycle that enters through the stomata of the leaf? • Carbon dioxide

  26. In addition to carbon dioxide, what goes into the Calvin cycle? • ATP and NADPH from phase 1

  27. What is the final product of the Calvin cycle? • glucose

  28. What is the process of releasing energy from glucose molecules called? • Cellular respiration

  29. What is the first phase of cellular respiration called? • glycolysis

  30. What is the second phase of cellular respiration called? • Kreb cycle or citric acid cycle

  31. What is the third phase of cellular respiration? • Electron Transport Chain

  32. What happens during glycolysis? • Sugars get broken down.

  33. What is the name of the molecule produced when glucose is split during glycolysis? • pyruvate

  34. In what part of the cell does glycolysis occur? • cytoplasm

  35. How many ATP’s does glycolysis produce? • 2 ATP’s

  36. Where does the Kreb cycle occur? • Within the inner membrane of the mitochondria (mitochondrion – singular)

  37. What does the Kreb cycle need? • Pyruvates, from glycolysis

  38. How many ATP’s does the Kreb cycle produce? • 2 ATP’s

  39. Where does the electron transport chain occur? • Along the outer membrane of the mitochondria.

  40. How many ATP’s does the electron transport chain produce? • 34 ATP’s
