Photo Cell Resp
Photosynthesis and Ceullular Respiration Vocabulary
| Term | Definition |
|---|---|
| Photosynthesis | synthesis of compounds with the aid of radiant energy (especially in plants) |
| autotroph | plant capable of synthesizing its own food from simple organic substances |
| heterotroph | an organism that depends on complex organic substances for nutrition |
| cellular respiration | the metabolic processes whereby certain organisms obtain energy from organic molecules |
| Chlorophyll | any of a group of green pigments found in photosynthetic organisms |
| Thylakoid | flattened sacs inside a chloroplast on which the light reactions of photosynthesis take place |
| electron transport chain | the most important stage of cellular respiration because it produces the most ATP |
| carbon fixation | the process by which inorganic carbon is converted to organic compounds by living organisms |
| calvin cycle | the light-independent reactions in photosynthesis that turn carbon dioxide into sugar |
| aerobic | depending on free oxygen or air |
| anaerobic | living or active in the absence of free oxygen |
| glycolysis | a metabolic process that breaks down carbohydrates and and release energy for the body in the form of ATP |
| Kreb’s Cycle | the second stage of cellular respiration; also known as the citric acid cycle |
| fermentation | the anaerobic breakdown of sugar into alcohol or acid |
| stroma | the dense colorless framework of a chloroplast |
| stomata | small pores that allow for gas exchange for carbon dioxide and Oxygen in plants |
| ADP | this is what an ATP molecule becomes after it has used one of its phosphate groups for energy |
| ATP | an organic compound and hydrotrope that provides energy to drive many processes in living cells |
| ATP synthase | an enzyme found in the mitochondria that creates ATP |
| grana | a stack of thylakoids found within the chloroplasts |
| lactic acid fermentation | an anaerobic metabolic process by which glucose is converted into cellular energy |
