Photosynthesis Check Point Questions Honors Biology

Light-Dependent PSII- Checkpoint Why does an electron become “excited”? What happens to the electron? Where is the electron’s final destination?

Light-Dependent PSII- Checkpoint What is the electron’s function? What happens to the H+? How does the chemiosmotic gradient create ADP from ATP?

Light-Dependent PSII- Checkpoint Why is H2O needed for photosynthesis?

Light-Dependent PSI- Checkpoint Why does an electron become “excited”? What happens to the electron? What energy molecule is produced because of PSI?

Light-Dependent Reaction- Checkpoint What are the three products of the Light Reaction? What is needed to make these products?

Dark Reaction- Checkpoint What two molecules start the Calvin cycle? What two molecules help the Calvin cycle conversions?

Dark Reactions- Checkpoint What are the two products of the Calvin cycle? How does the cycle continue?
