  1. CO2 CO2 CO2 CO2 CO2 CO2 enters the leaf

  2. C O2 C O2 C O2 C O2 C O2 O2 leaves the leaf

  3. H2O H2O H2O H2O H2O C C C C C O2 O2 O2 O2 O2 Sunlight provides the energy to join the Carbon atoms together H2O enters the leaf

  4. H2O H2 O C C C C C H2O H2O H2O O2 O2 O2 O2 O2 H2O contributes Hydrogen and Oxygen to the building of the Glucose molecule by the plant

  5. Glucose contains stored energy from the sun. C6H12O6 + 6O2 6CO2 + 6H2O Stored energy From the sun

  6. H2O + O2 CO2 Energy from the sun is what it took to build glucose and it retains a portion of that energy in the bonds to be used later by heterotrophs Glucose is stored C6H12O6 + 6O2 6CO2 + 6H2O Stored energy From the sun Photosynthesis

  7. C6H12O6 Sugars are stored in fruits and to a lesser extent in Vegetables (not sweet) and as starch in grains (not sweet)

  8. Leafy vegetables and grasses don’t contain much if any simple Sugars like glucose and no starch. Sugar is used to form cellulose which is not digestible by humans But Cows and Horses can digest it.

  9. 6CO2 + 6H2O C6H12O6 + 6O2

  10. Apple trees are Autotrophs They make their own food through photosynthesis Apples are full of glucose from photosynthesis

  11. Glucose is consumed by a heterotroph

  12. Glucose enters the blood supply and travels to a cell in the body.

  13. Glucose is used by heterotrophs for energy by breaking down the glucose molecule in the cell to release the energy stored in the bonds. Stored energy From the sun Cellular Respiration 6CO2 + 6H2O C6H12O6 + 6O2

  14. When we breathe out, we exhale H2O and CO2 O2 enters the cell to help break down glucose O2 ATP H2O H2O ATP Glucose ends up as H2O and CO2 ATP CO2 CO2 H2O H2O CO2 Glucose is broken down by the cell to provide energy in the form of ATP. ATP is used to keep the cell alive, to drive all cell activities CO2 H2O ATP ATP H2O CO2 ATP CO2 ATP Cellular Respiration 6CO2 + 6H2O C6H12O6 + 6O2
