| Term | Definition |
|---|---|
| Adenosine triphosphate (ATP) | compound used by cells to store and release energy |
| Heterotroph | organisms that contain food by consuming other living things; also called a consumer |
| Autotroph | organisms that is able to capture energy from the sunlight of chemicals and use it to produce its own food from inorganic compounds: also called a producer |
| Photosynthesis | process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy--rich carbohydrates such a as sugars and starches |
| Pigment | light-absorbing molocules used by plants to gather the sun's energy |
| Chlorophyll | principal pigment of plants and other photosynthetic organisms |
| Thylakoid | sac-like photosynthetic membranes found in chloroplasts |
| Stroma | principal pigment of plants and other photosynthetic organisms |
| NADP+ | (Nicotinamide Adenine Dinucleotide Phosphate): carrier molecule that transform high-energy electrons to chlorophyll to other molocules |
| Light-dependent reactions | set of reactions in photo synthesis that use energy from light to produce ATP and NADPH |
| Light-independent reactions | set of reactions in photo synthesis that does not require light; energy from ATP and NADPH is used to build high-energy compounds such a as sugar; also called Calvin cycle |
| Photosystem | custer of chlorophyll and proteins found in thylakoids |
| Electron transport chain | series of electron carrier proteins that shuttle high-energy electrons during APT-generating reactions |
| ATP synthase | cluster of proteins that spam the cell membrane and allow hydrogen ions (H+) to pass through it |
| Calvin cycle | light-independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high-energy compounds such as sugar |
