  1. 1. How does the energy from <br />the sun make it into our<br />Belly??<br />By: Jonathan<br />&<br />Seth<br />
  2. 2. First through…<br />
  3. 3. Photosynthesis<br />
  4. 4. 6CO2 + 6H2O + energy --&gt;  6O2 + C6H12O6<br />Plants absorb a common gas called carbon dioxide, pull water up through their roots and use light to make sugar. Plants use the sugar to grow. Plants give off oxygen as a by-product. The green parts of the plant makes the sugar and oxygen.<br />
  5. 5. Sun<br />Photosynthetic cells may have thousands of chloroplasts . Chloroplasts in plant & algal cells absorb light energy from the sun during the light dependent reactions <br />
  6. 6. In the Chloroplasts<br />Light Traveling<br />When light strikes an object, it is absorbed, transmitted, or reflected . When all colors are absorbed, the object appears black<br />When all colors are reflected, the object appears white<br />If only one color is reflected (green), the object appears that color such as the Chlorophyll.<br />
  7. 7. In the thylakoid happens light dependent reactions. This system depends on sunlight for activation energy.<br />Light is absorbed by chlorophyll a which &quot;excites&quot; the electrons in the chlorophyll molecule.Electrons are passed through a series of carriers and adenosine triphosphate or ATP (energy) is produced.<br />H2O O2 + ATP + NADPH2<br />
  8. 8. Light is absorbed by the antenna pigments of photosystems II and I<br />These excited electrons activate P700 in photosystem I which helps reduce NADP+ to NADPH//NADPH is used in the Calvin cycle. <br />Still in the thylakoid<br />The absorbed energy is transferred to the reaction center pigment, P680 in photosystem II, P700 in photosystem I<br />
  9. 9. CO2 diffuses into the stroma from surrounding cytosol <br />An enzyme combines a CO2 molecule with a five-carbon carbohydrate called RuBP <br />PGAL serves as the starting material for the synthesis of glucose and fructose <br />Glucose and fructose make the disaccharide sucrose, which travels in solution to other parts of the plant <br />Alternate<br />Cycle<br />Calvin<br />Cycle<br />Each PGA molecule receives a phosphate group from a molecule of ATP <br />
  10. 10. And the plant GROWS!!!<br />
  11. 11. Everyone needs ENERGY<br />
  12. 12. So after getting a Tan<br />
  13. 13. Boneshikwa Gets hungry<br />
  14. 14. So she goes out to eat the grass<br />
  15. 15. The grass that she eats gives her the energy she needs for her body to function otherwise known as…….<br />
  16. 16. Cellular Respiration<br />
  17. 17. Energy can be transformed from one form to another like photosynthesis converts light energy to chemical energy in which the turkey ate in the grass.<br />
  18. 18. The energy process<br />happens in the<br />Mitochondria<br />
  19. 19. ATP is energy carrying molecule used by cells to fuel their cellular processes.<br />ATP is composed of an adenine base, ribose sugar, & 3 phosphate (PO4) groups.<br />
  20. 20. ATP is made & used continuously by cells<br />Every minute all of an organism&apos;s ATP is recycled<br />
  21. 21. Enzymes help break & reform these high energy PO4 bonds in a process called substrate-level phosphorylation.<br />When the high-energy phosphate bond is broken, it releases energy, a free phosphate group, & ADP.<br />
  22. 22. Second Energy<br />Carriers<br />
  23. 23. Third Energy carrier<br />FADH2<br />
  24. 24. Mitochondria Has<br />Electron Transport Chain takes place in cristae<br />Space inside cristae is called the matrix & contains DNA & ribosomes also the Krebs cycle takes place in it<br />
  25. 25. The energy in one glucose molecule may be used to produce 36 ATP it involves a series of 3 reactions…….Glycolysis, Kreb&apos;s Cycle, & Electron Transport Chain.<br />
  26. 26. NADH is energy<br />2 ATP added to glucose (6C) to energize it.<br />Glucose split to 2 PGAL (3C).<br />
  27. 27. If no oxygen is available to the cell (anaerobic), the pyruvate will be fermented<br />Pyruvic acid from glycolysis diffuses into matrix of mitochondria & reacts with coenzyme<br />
  28. 28. Acetyl Co-A (2C) enters the Kreb&apos;s Cycle & joins with Oxaloacetic Acid (4C) to make Citric Acid <br />Oxaloacetic acid is regenerated to start the cycle again<br />Citric acid is oxidized releasing CO2 , free H+, & e- and forming ketoglutaric acid <br />In Aerobic respiration<br />Happens the Krebs Cycle<br />Free e- reduce the energy carriers NAD+ to NADH2 and FAD+ to FADH2<br />
  29. 29. In the Electron transport<br />Chain<br />A concentration gradient of H+ between the inner & outer mitochondrial membrane occurs<br />H+ concentration gradient causes the synthesis of ATP by chemiosmosis<br />Energized e- & H+ from the 10 NADH2 and 2 FADH2 are transferred to O2 to produce H2O<br />
  30. 30. This Whole process is the functions that keep the plant life alive and healthy. It also makes it look yummy to Boneshikwa the turkey and she eats.<br />
  31. 31. Then she gets to be a………<br />
  32. 32. And becomes<br />
  33. 33. DINNER!!<br />
  34. 34. Then we eat the turkey!<br />
  35. 35. And that’s how nuclear<br /> energy enters <br />our body<br />
  36. 36. QUIZ!!!<br />
  37. 37. How does Photosynthesis start??<br />-With the energy from the sun<br />
  38. 38. Where does the energy go? <br />-Chloroplast<br />
  39. 39. What light is reflected off the Chloroplasts?<br />-Green<br />
  40. 40. Light is absorbed by light pigments….?<br />-Photosystems I and II<br />
  41. 41. The_____cycle is in Photosynthesis?<br />-Calvin cycle<br />
  42. 42. What happens in the mitochondria?<br />-The energy process<br />
  43. 43. What is the third energy carrier?<br />-FADH2<br />
  44. 44. What space in the mitochondria contain DNA and ribosomes?<br />-Matrix<br />
  45. 45. The energy in one glucose molecule may be used to produce how many ATPs?<br />-36<br />
  46. 46. What cycle is in Cellular Respiration?<br />-Krebs Cycle<br />
  47. 47. Great Job Your done!!!!!<br />
