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 |
