| Photosynthesis | Process by which certain organisms use energy from sunlight to synthesize food |
| autotroph | an organism that makes its own food |
| heterotroph | organisms that must obtain its food from the environment |
| oxygen | a by-product of photosynthesis necessary to most living organisms |
| if all photosynthetic processes came to a hault | there would be no more oxygen and everything would die out |
| glucose and oxygen | products of photosynthesis |
| carbon dioxide, water, light, chlorophyll | reactants of photosynthesis |
| chlorophyll | most important pigment in photosynthesis, captures energy in sunlight and manufactures carbs |
| accessory pigments | enable plants to use more of the suns energy; carotenes, xanthophylls, carotenoids, etc. |
| green + yellow | color of chlorophyll b/c it REFLECTS them |
| plastids | class of organelles that chloroplasts belong |
| grana | stacks of thylakoids and chloroplasts |
| thylakoid | tiny membrane bound sack containing the chlorophyll in the chloroplasts |
| light energy is converted to chemical energy | when it excites certain electrons in the chlorophyll atom |
| photolysis | the splitting of water molecules by energy originally coming from light |
| NADP | hydrogen atoms released by the splitting of water are picked up by this coenzyme |
| starch | how excess glucose formed in photosynthesis is stored |
| carbon dioxide + atp + NADPH | raw materials necessary for dark rxns |
| carbon fixation | synthesis of organic compounds from carbon dioxide + hydrogen |
| products of light rxn | ATP, NADPH, oxygen |
| stroma | enzyme containing fluid |
| main purpose of photosystem II | to produce ATP |
| Ferridoxin | the coenzyme by which the electron is accepted |
| coenzyme | on the electron transport chain |
| energy of the electron | used to connect ADP + a phosphate to form ATP |
| main purpose of photosystem I | to produce NADPH |
| role of water | supplies electrons to chlorophyll in photosystem II that had been realeased when they were struck by light, supplies hydrogen to from NADPH (split by enzymes located on the thylakoid membrane + by light |
| main product of dark rxn | glucose after 6 turns |
