| Where does respiration take place? | all living cells |

| What type of food contains most energy? | fats |
| What does sodium hydroxide do? | absorb carbon dioxide |

| fermentation in animals stage 2 | glucose is broken down in the cytoplasm into lactate, this releases very little energy |
| ATP | the molecule that stores energy from glucose in the cell |
| What happens when oxygen becomes available after fermentation in animal cells? | lactate is converted back into pyruvate and enters the aerobic respiration pathway |
