Proteins 0.0 / 5 ? BiologyEnzymes and digestionGCSEAQA Created by: AmberCoombesCreated on: 10-11-15 19:29 What are proteins made up of? Proteins are made up of amino acids (small molecules) joined together into long protein chains. 1 of 19 What are biological catalysts called? Biological catalysts are called enzymes. 2 of 19 What is denaturing? Denaturing is when heat changes the shape of an enzyme. 3 of 19 What happens when an enzyme is denatured? When an enzyme is denatured, the substrate will no longer fit into the active site. 4 of 19 What are digestive enzymes produced by? Digestive enzymes are produced by specialised cells in glands and in the lining of the gut. 5 of 19 What happens when the digestive enzymes are produced? They come in contact with food molecules and the enzymes catalyse the breakdown of the large food molecules into smaller molecules. 6 of 19 What is the most common carbohydrate? The most common carbohydrate is starch. 7 of 19 What are the enzymes that break down carbohydrates called? The enzymes that break down carbohydrates are called carbohydrases. 8 of 19 Where is starch broken down into sugar and which enzyme catalyses is? Starch is broken down into sugar in the mouth and small intestine. The enzyme which catalyses this reaction is called amylase. 9 of 19 Where is amylase produced? Amylase is produced in the salivary glands, the small intestine and the pancreas. 10 of 19 When does the digestion of starch take place? The digestion of starch starts in the mouth, then to the small intestine via the oesophagus. 11 of 19 What is breaking down protein catalysed by? Breaking down protein is catalysed by protease enzymes. 12 of 19 What are protease produced by? Protease are produced by the stomach, pancreas and small intestine. 13 of 19 Where does the breakdown of proteins into amino acids happen? The breakdown of proteins into amino acids happens in the stomach and small intestine. 14 of 19 What happens in the salivary glands? Amalayse enzyme breaks down starch to sugar 15 of 19 Where does digestion take place? Digestion takes place in the stomach 16 of 19 Where is lipase produced? Lipase is produced in the small intestine and in the pancreas 17 of 19 Where is most of the starch you eat digested? Most of the starch you eat is digested in the small intestine 18 of 19 What does the small intestine do? The small intestine breaks down the fat to fatty acids and glycerol 19 of 19
