| Term | Definition |
|---|---|
| Autotroph | organisms that make their 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 | All living things need |
| 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 |
| Heterotrophs | are living things that cannot make their own food. |
| Photosynthesis | process of using the energy in sunlight to make food |
| Producer | Autotrophs are also called |
| Calvin Cycle | second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NAPH, 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 trans chain | series of electron-transport molecules that pass high-energy electrons from molecule to molecule and capture their energy |
| grana | Each chloroplast contains neat stacks |
| 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 |
| Aerobic respiration | type of cellular respiration that requires oxygen |
| Anaerobic respiration | type of cellular respiration that does not require oxygen |
| glycolysis | first stage of cellular respiration in which glucose is split, in the absence of oxygen , to form two molecules of pyruvate (pyruvic acid) and two (net) molecules of ATP |
| Krebs cycle | second stage of aerobic respiration in which two pyruvate (pyruvic acid) molecules from the first stage react to form ATP,NADH, and FADH2. |
| alcoholic fermentation | type of anaerobic respiration that includes glycolysis followed by the conversion of pyruvic acid to ethanol acid and the formation of NAD+ |
| fermentation | It involves glycolysis but not the other two stages of aerobic respiration. |
| lactic acid fermentation | type of anaerobic respiration that includes glycolysis followed by the conversion of pyruvic acid to lactic acid and the formation of NAD. |
