| Question | Answer |
|---|---|
| A compound consisting of an adenosine molecule bonded to three phosphate groups, present in all living tissue | adenosine triphosphate (ATP) |
| An organism deriving its nutritional requirements from complex organic substances. | heterotroph |
| An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. | autotroph |
| The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. | photosynthesis |
| The natural coloring matter of animal or plant tissue. | pigment |
| The light-dependent reactions, or light reactions, are the first stage of photosynthesis. | light-dependent reactions |
| 1.A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. | chlorophyll |
| 1.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 | thylakoid |
| 1.The supportive tissue of an epithelial organ, tumor, gonad, etc., consisting of connective tissues and blood vessels | stroma |
| Nicotinamide adenine dinucleotide phosphate | NADP+ |
| The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. | light-independent reactions |
| 1.A biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. | photosystem |
| An electron transport chain (ETC) couples a reaction between an electron donor (such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a membrane, through a set of mediating biochemical reactions | electron transport chain |
| ATP synthase is a general term for an enzyme that can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate by using a form of energy | ATP synthase |
| The Calvin cycle or Calvin–Benson cycle or Reductive Pentose Phosphate cycle is a series of biochemical reactions that take place in the stroma of chloroplasts in photosynthetic organisms | Calvin cycle |
