Presentation Transcript

  1. S H H H H H+ e- O O H O how plants produce oxygen Photosynthesis the source of sweetness on Earth– process by which green plants create carbohydrates, transforming sunshine into sugar, storing energy in a chemical molecule photon Water Splitting Clock click to continue click to begin This process begins with two water molecules… is captured A photon of sunlight releasing one hydrogen as anelectron and aproton proton hydrogen ion electron S0 water water

  2. S H H H+ e- e- O O H +H O Photosynthesis photon the source of sweetness on Earth– process by which green plants create carbohydrates, transforming sunshine into sugar, storing energy in a chemical molecule Water Splitting Clockhow plants produce oxygen S1 click to continue electron A secondphoton is captured releasing an electron proton electron S0 water water

  3. S H H H H+ H+ e- e- e- O +H O O Photosynthesis photon S2 Water Splitting Clockhow plants produce oxygen electron hydrogen ion proton S1 click to continue electron A third photon is captured releasing onehydrogen as anelectron and aproton proton electron S0 water water

  4. S H H+ H+ H+ e- e- e- e- O +H O O Photosynthesis photon S2 Water Splitting Clockhow plants produce oxygen electron proton S1 S3 hydrogen ion proton click to continue electron electron A fourth photon is captured releasing one hydrogen as anelectron and aproton proton electron S0 water water

  5. H+ H+ H+ H+ e- e- e- e- O O O O +H O Photosynthesis S2 Water Splitting Clockhow plants produce oxygen electron proton S1 S3 proton click to continue electron electron Last, onehydrogen is released as a proton and one oxygen molecule is released proton proton electron S0 S4 oxygen water water

  6. H+ H+ H+ H+ e- e- e- e- Photosynthesis S2 Water Splitting Clockhow plants produce oxygen electron proton S1 S3 proton click to continue electron electron 4 electrons 4 protons and used by the plant cell to make carbohydrate proton proton electron S0 S4 water oxygen water
