| Term | Definition |
|---|
| light reactions | steps in photosynthesis that directly require light to operate |
| Calvin cycle | steps in photosynthesis that do NOT directly require light |
| oxygen | chemical product of light reaction; considered waste product; produced when water is split |
| water | chemical reactant of light reaction |
| carbon dioxide | chemical reactant of Calvin cycle |
| sugar (e.g. glucose) | chemical product of Calvin cycle |
| oxygen and sugar | final chemical products of photosynthesis |
| carbon dioxide and water | chemical reactants of photosynthesis |
| ATP and NADPH | high energy products made by the light reactions and used in the Calvin cycle |
| ADP & P & NADP+ | low energy products made by the Calvin cycle and made back into high energy products in the light reactions |
| electron transport chain | passes electrons down a series of proteins and pumps hydrogen ions from stroma into thylakoid space |
| ATP synthase | protein on thylakoid membrane that makes ATP when hydrogen ions pass through it from thylakoid space to stroma |
| photosystem | cluster of pigment molecules in the thylakoid membrane that absorb light |
| reaction center | portion of the photosystem that contains the chlorophyll and primary electron acceptor |
| primary electron acceptor | portion of the reaction center that grabs the excited electron from the excited chlorophyll |
| photosystem 1 | NADPH producing photosystem |
| photosystem 2 | photosystem that splits water into hydrogen ions, electrons, and oxygen |
| RuBP | molecule that grabs and fixes carbon dioxide in the Calvin cycle |
| G3P | molecule that is made in the Calvin cycle; glucose is formed when two of these molecules combine |
| starch | what is made when excess sugar is made in the Calvin cycle |
