| 11486619821 | photosynthesis (definition) | process of harnessing light energy to build carbohydrates |  | 0 |
| 11486619826 | photosynthesis (equation) | 6 CO2 + 6 H2O + light energy --> C6H12O6 + 6 O2 | 1 | |
| 11486619827 | autotroph | organism that can capture energy from sunlight or chemicals and use it to produce its own food (producer) |  | 2 |
| 11486619828 | heterotroph | organism that cannot produce its own food and therefore obtains it by consuming other living things (consumer) |  | 3 |
| 11486619831 | light-dependent reactions | 1st step of photosynthesis during which light energy is captured and used to synthesize ATP and NADPH |  | 4 |
| 11486619832 | light-independent reactions | 2nd step of photosynthesis during which CO2 is incorporated into a sugar molecule using energy and electrons from ATP and NADPH |  | 5 |
| 11486619833 | thylakoid membranes of chloroplasts | location of light-dependent reactions | 6 | |
| 11486619834 | stroma of chloroplasts | location of light-independent reactions | 7 | |
| 11486619835 | G3P | carbon product of the light-independent reactions that is the precursor of glucose, as well as other carbs and lipids |  | 8 |
| 11486619845 | photosystems | photosynthetic pigments embedded in the thylakoid membrane that absorb and reflect specific wavelengths of light |  | 9 |
| 11486619846 | water | splitting this molecule provides electrons which are excited by light in the first step of photosynthesis | 10 | |
| 11486619847 | oxygen | released as a byproduct of splitting water in the first step of photosynthesis | 11 | |
| 11486619849 | ATP synthase | enzyme that synthesizes ATP using chemiosmosis |  | 12 |
| 11486619852 | carbon dioxide | molecule reduced in Calvin cycle to produce sugar; source of most of the mass of a plant | 13 | |
| 11486619855 | glucose and oxygen | products of photosynthesis | 14 | |
| 11486619856 | carbon dioxide and water | reactants of photosynthesis | 15 | |
| 11486619859 | thylakoid space | site of proton gradient built up in photosynthesis | 16 | |
| 11486619862 | NADPH | high energy electron carrier formed by the light reaction in photosynthesis that provides reducing power for the Calvin Cycle |  | 17 |
| 11486619870 | RuBisCo | enzyme with affinity for both CO2 and O2 that catalyzes first step of Calvin cycle by adding CO2 to ribulose bisphosphate (RuBP) | 18 | |
| 11486619871 | stomata | pore-like openings on underside of leaves that allow gases (CO2 and O2) and water to diffuse in and out |  | 19 |
| 11486619873 | photorespiration | occurs on hot, dry days when stomata close, O2 accumulates and Rubisco fixes O2 rather than CO2, using up ATP, O2 and sugars |  | 20 |
| 11486619874 | C3 plants | traditional plants that use RuBisCo in Calvin Cycle |  | 21 |
| 11486619875 | C4 plants | spatially separate carbon fixation from Calvin Cycle to reduce photorespiration; use PEP carboxylase instead of RuBisCo to fix CO2 |  | 22 |
| 11486619876 | CAM plants | temporally separate carbon fixation (day) and Calvin Cycle (night); use PEP carboxylase instead of RuBisCo to fix CO2 |  | 23 |
