| Question | Answer |
| What do you call a molecule that fits into the active site of an enzyme? | A Substrate |
| What does LIPASE help break down? | Lipids (fats and oils) into fatty acids and glycerol |
| What does AMYLASE help break down? | Starch into sugars |
| What does PROTEASE help break down? | Proteins into amino acids |
| Where is BILE produced? | The liver |
| What does BILE do? | Bile neutralises acidic food and emulsifies fats |
| Where is BILE stored? | The gall bladder |
| Where is AMYLASE produced? | The salivary glands, the pancreas and the small intestines |
| Where is PROTEASE produced? | The stomach, the pancreas and the small intestines |
| Where is LIPASE produced? | The pancreas and the small intestines |
| What are ENZYMES? | Enzymes are proteins and are classed as biological catalysts |
| What are proteins? | Long chains of amino acids |
| What are some everyday uses for enzymes? | Baby foods, biological detergents, convert starch syrups into sugar syrups, convert glucose syrup into fructose syrup, change the flavour of food, extract juice from fruit, making medical products... |
| What is a catalyst? | Something which speeds up the rate of reaction while remaining chemically unchanged. |
| What happens if the temperature gets too high or too low? | If this happens the temperature will change the shape of the active site meaning the enzyme no longer fits and so the enzyme is no longer useful. This means the enzyme has denatured. |
| What happens if the PH level gets too high or too low? | The forces holding the enzyme molecule together will get weak and the enzyme will denature. |
| What is the active site of the enzyme? | A specific shape in the enzyme which fits together with other specific shaped molecules. |
