CELL RESPIRATION
Biology II-13
| Term | Definition |
|---|---|
| Aerobic Respiration | cellular respiration with oxygen present to make 32-38 ATP |
| Anaerobic Respiration | cellular respiration without oxygen (fermentation) only makes 2ATP, plus CO2 and alcohol or lactic acid |
| Glycolysis | first step in all cell respiration to break glucose into two 3-carbon molecules |
| Krebs Cycle | second step in aerobic respiration to complete break down of two 3-carbon molecules into CO2 and makes energy carriers for ETC |
| Electron Transport Chain | third step in aerobic respiration to use energy carriers to make most ATP, uses oxygen and produces water |
| Fermentation | type of anaerobic respiration that makes CO2 and alcohol from sugars |
| Lactic Acid | waste product from anaerobic respiration in ANIMALS when oxygen in low supply; make muscles sore |
| ATP | temporary high energy molecule for cell fuel with three phosphates |
| cell respiration | chemical reactions to transfer energy stored in sugars and other food to ATP (fuel molecules that all cells use); releases carbon dioxide |
