| Term | Definition |
|---|---|
| adenosine triphosphate | compound used by cells to store and release energy |
| heterotroph | organism that obtain food by consuming other living things; also called a consumer |
| autotroph | orgasm that is able to capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds also called a producer |
| photosynthesis | the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. |
| pigment | the natural coloring matter of animal or plant tissue. |
| chlorophyll | a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring. |
| thylakoid | each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana. |
| stroma | the supportive tissue of an epithelial organ, tumor, gonad, etc., consisting of connective tissues and blood vessels. |
| NABP+ | a coenzyme that functions as a universal electron carrier, |
| light-dependent | chemical reactions that convert carbon dioxide and other compounds into glucose |
| reactions | an action performed or a feeling experienced in response to a situation or event. |
| light-independent | a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide. |
| reactions | an action performed or a feeling experienced in response to a situation or event. |
| photosystem | a biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. There are two such mechanisms ( photosystems I and II ) involving different chlorophyll-protein complexes. |
| electron Transport chain | a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation |
| APT synthase | an enzyme that produces adenosine triphosphate (ATP), the cell's primary energy storage and transfer molecule |
| Calvin cycle | the cycle of enzyme-catalyzed dark reactions of photosynthesis that occurs in the chloroplasts of plants and in many bacteria and that involves the fixation of carbon dioxide and the formation of a 6-carbon sugar. |
