| Energy | What respiration provides. It is needed for life processes |
| Aerobic | Type of respiration which uses oxygen |
| Metabolic rate | Measurement of how fast our body is using energy |
| Oxygen | The rate at which this gas is consumed tells us our metabolic rate |
| Glucose | The preferred fuel for respiration |
| Burning | Unlike respiration, this process is uncontrolled, produces flames and is often incomplete |
| Calorimetry | The type of experiment used to measure the energy value of foods |
| Water | A liquid produced by aerobic respiration |
| Enzymes | Control the rate of respiration |
| Mitochondria | Where aerobic respiration takes place |
| Lactic acid | Poison produced by anaerobic respiration in humans |
| Anaerobic | Type of respiration which doesn't use oxygen |
| More energy | Why do organisms use aerobic respiration when they can |
| Oxygen debt | Phrase used to describe the oxygen needed to break down lactic acid after exercise |
| Muscles | Site of anaerobic respiration in humans, where lactic acid builds up |
| Fatigue | Effect of lactic acid build up in muscles |
| Ethanol | Poison made by yeast during anaerobic respiration |
| Carbon dioxide | Gas made by yeast during anaerobic respiration |
| Bread | Food which is made using anaerobically respiring yeast |
| Alcohol | Common name for ethanol |
| Beer | Drink made using anaerobically respiring yeast and barley |
| Wine | Drink made using anaerobically respiring yeast and fruit |
| Poisoned | What happens to yeast cells when the ethanol builds up |
| Fermentation | Another name for anaerobic respiration in yeast |
| Liver | Where lactic acid is broken down |
| Blood | Where cells get their oxygen and glucose from |
| Photosynthesis | The equation for aerobic respiration is the reverse of the equation for this process |
| Exercise | A common cause of anaerobic respiration |
| Fungi | Yeast is a member of this group of organisms |
| Yeast | Anaerobically respiring organism, used to make beer and bread |
