1. Photosynthesis An Animated Tour

2. O2O2 Photo- system I ETCCHEMIOS H+H+ e-e- Photo- system II Thylakoid Membrane Stroma H2OH2O Light energy is captured by PS-II and the energy is used to split water, releasing oxygen to the air Releasing electrons (e - ) and hydrogen ions (H + )

3. Photo- system I ETCCHEMIOS H+H+ e-e- Photo- system II Thylakoid Membrane Stroma ATPNADPH The H+ ions and electrons power ETC & CHEMIOSMOSIS and produce ATP and NADPH

4. Glucose Photo- system I ETCCHEMIOS Photo- system II Thylakoid Membrane Stroma The ATP and NADPH formed in the LIGHT DEPENDENT REACTIONS is used to power the CALVIN CYCLE Calvin Cycle CO 2 Carbon Dioxide is “FIXED” in this step to produce CARBOHYDRATE ATPNADPH

5. GlucoseCO 2 Calvin Cycle Calvin Cycle Photo- system I ETCCHEMIOS Photo- system II ATPNADPH Thylakoid Membrane Stroma Six CO2 molecules needed to “turn” the cycle to produce one glucose molecule

6. Photo- system II Calvin Cycle GlucoseCO 2 Photo- system I ETCCHEMIOS ATPNADPH Thylakoid Membrane Stroma THE TOTAL TACO e-e- H+H+ H2OH2OO2O2
