| 3 parts of Cyclic Photophosphorylation are ______ + ______ + _______. | ETS (Electron Transport System), Photosystem I, Acceptor Molecule |
| What is the name for a packet of light energy? | A Photon |
| The reactant gas in photosynthesis. | Carbon Dioxide |
| Why does photolysis have to occur? | To replace electrons lost in photosystem II. |
| How many times is carbon fixed in C4 plants? | Two times |
| What is the name of the molecule to which carbon dioxide is first "fixed" to in the Calvin Benson cycle? | Ribulose Biphosphate |
| During the dark reactions, ATP provides the _______ and NADPH provides the _______ for building a sugar. | energy; H+ and electrons |
| Another name for the Calvin Benson Cycle (Dark Reactions). | The Light Independent Reactions |
