Temperature and pH 1 of 10 Where is amylase produced? Salivary glands, pancreas and the small intestine 2 of 10 What are the products of lipid (fat) digestion? Fatty acids and glycerol 3 of 10 Which acid is produced by the stomach? Hydrochloric acid 4 of 10 What is the function of bile? To neutralise acid from the stomach 5 of 10 Why are proteases used in baby foods? They predigest food so the baby can absorb it more easily 6 of 10 Give two types of reaction controlled by enzymes in the cells Breaks down large molecules into small ones and changes one molecule into another 7 of 10 Why does increasing the temperature increase the rate of a reaction? The molecule have more energy so they move around faster and collide more often so the reaction is quicker. 8 of 10 Give one advantage and one disadvantage of using enzymes in the industry Less energy is needed and costly to produce 9 of 10 Why do biological washing powders work more efficiently than non-biological powders? The enzymes speed up the digestion of stains from food and they work in lower temperatures that saves money 10 of 10
