Presentation Transcript

  1. Photosynthesis The Calvin Cycle

  2. Calvin Cycle • occurs in the stroma • 3 phases • carbon fixation • reduction reactions • RuBP regeneration

  3. Calvin CycleImage from: http://schoolworkhelper.net/2010/07/the-calvin-cycle/ • for every 3 CO2 molecules that enter the Calvin cycle, 1 G3P molecule is produced • 5 G3P molecules are used to regenerate RuBP

  4. Animations • Animation of Calvin cycle: http://www.science.smith.edu/departments/Biology/Bio231/calvin.html • Narrated animation with quiz: http://highered.mcgraw-hill.com/sites/0070960526/student_view0/chapter5/animation_quiz_1.html

  5. Energy Requirements • for every 1 G3P molecule that comes out of the Calvin cycle, 9 ATP and 6 NADPH are needed

  6. Light Reactions RecapImage from: http://twinkle_toes_engineering.home.comcast.net 2 H2O ---> 4e- ---> 12 H+ ---> 3 ATP + 2 NADPH

  7. Tracking Atoms in Photosynthesis6CO2 + 12H2O C6H12O6 + 6H2O + 6O2
