| Term | Definition |
|---|---|
| autotroph | organism that makes its own food |
| cellular respiration | process in which cells break down glucose and make ATP for energy |
| consumer | organism that consumes other organisms for food |
| energy | ability to do work |
| food | organic molecules such as glucose that organisms use for chemical energy |
| glucose | simple carbohydrate with the chemical formula C6H12O6 that is the nearly universal food for life |
| heterotroph | organism that gets food by consuming other organisms |
| photosynthesis | process of using the energy in sunlight to make food (glucose) |
| producer | organism that produces food for itself and other organisms |
| Calvin cycle | second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NADPH, to make glucose |
| chemosynthesis | process of using the energy in chemical compounds to make food |
| chlorophyll | green pigment in a chloroplast that absorbs sunlight in the light reactions of photosynthesis |
| electron transport chain | series of electron-transport molecules that pass high-energy electrons from molecule to molecule and capture their energy |
| grana | within the chloroplast, consists of sac-like membranes, known as thylakoid membranes |
| light reactions | first stage of photosynthesis in which light energy from the sun is captured and changed into chemical energy that is stored in ATP and NADPH |
| photosystem | group of molecules, including chlorophyll, in the thylakoid membrane of a chloroplast that captures light energy |
| stroma | space outside the thylakoid membranes of a chloroplast where the Calvin cycle of photosynthesis takes place |
| thylakoid membrane | membrane in a chloroplast where the light reactions of photosynthesis occur |
