Terms | Definitions |
|---|---|
 Photosynthesis | two-phase reaction (or 2 phase anabolic pathway) in which the Sun's light energy is converted to chemical energy for use by the cell. |
| Adenosine triphosphate (ATP) | energy-carrying biological molecule, which, when broken down, drives cellular activities. |
| Autotroph | Organism that captures energy from sunlight or inorganic substances to produce its own food. |
| Heterotroph | Organism that cannot make its own food and gets its nutrients and energy requirements by feeding on other organisms. |
| Aerobic respiration | metabolic process in which pyruvate is broken down and electron-carrier molecules are used to produce ATP through electron transport. |
| Anaerobic process | a metabolic process that does not require oxygen. |
| Calvin cycle | light-independent reactions during phase two of photosynthesis in which energy is stored in organic molecules as glucose. |
| Cellular respiration | catabolic pathway in which organic molecules are broken down to release energy for use by the cell. |
| Fermentation | process in which NAD+ is regenerated, allowing cells to maintain glycolysis in the absence of oxygen. |
| Glycolysis | anaerobic process; first stage of cellular respiration in which glucose is broken down into two molecules of pyruvate. |
| Granum | one of the stacks of pigment-containing thylakoids in a plant's chloroplasts. |
| Krebs cycle | series of reactions in which pyruvate is broken down into carbon dioxide inside the mitochondria of cells; also called the tricarboxylic acid cycle and the citric acid cycle. |
| NADP+ | in photosynthesis, the major electron carrier involved in electron transport. |
| Stroma | fluid-filled space outside the grana in which light-dependent reactions take place. |
| Thylakoid | in chloroplasts, one of the stacked, flattened, pigment-containing membranes in which light-dependent reactions occur. |
