| Question | Answer |
|---|---|
| calorie | the amount of energy needed to raise one gram of water 1 degree Celcius |
| Calorie | 1000 calories; kiolcalorie; used on food labels |
| glycolysis | releases small amounts of energy; leads to other processes that release LARGE amounts of energy; oxygen and glucose go in; first process of cellular respiration; takes place in the cytoplasm |
| cellular respiration | process that releases energy by breaking down food molecules in the presence of oxygen. Involves in order: glycolysis, Krebs cycle, and Electron Transport Chain |
| fermentation | If oxygen is not present, glycolysis is followed by fermentation. (anaerobic) two kinds: alcoholic and lactic acid. |
| Krebs cycle | 2nd process of cellular respiration. It takes place in the mitochondria; needs oxygen; During this cycle, pyruvic acid is broken down into Carbon dioxide in a series of energy-releasing reactions, a.k.a. critic acid cycle |
| Electron Transport Chain |
