AQA Enzymes
Cards in this deck (17)
- 1What do you call a molecule that fits into the active site of an enzyme?A Substrate
- 2What does LIPASE help break down?Lipids (fats and oils) into fatty acids and glycerol
- 3What does AMYLASE help break down?Starch into sugars
- 4What does PROTEASE help break down?Proteins into amino acids
- 5Where is BILE produced?The liver
- 6What does BILE do?Bile neutralises acidic food and emulsifies fats
- 7Where is BILE stored?The gall bladder
- 8Where is AMYLASE produced?The salivary glands, the pancreas and the small intestines
- 9Where is PROTEASE produced?The stomach, the pancreas and the small intestines
- 10Where is LIPASE produced?The pancreas and the small intestines
- 11What are ENZYMES?Enzymes are proteins and are classed as biological catalysts
- 12What are proteins?Long chains of amino acids
- 13What 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...
- 14What is a catalyst?Something which speeds up the rate of reaction while remaining chemically unchanged.
- 15What 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.
- 16What 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.
- 17What is the active site of the enzyme?A specific shape in the enzyme which fits together with other specific shaped molecules.
