Muscular, Glandular, Epithelial. 1 of 24 Order these in size: Organs, Tissues, Organ System. Tissues, Organs, Organ Systems. 2 of 24 What does a muscular tissue do in a stomach? Churns up the food so it can be digested. 3 of 24 Name the organs that are in the digestive system. Stomach, Liver, Pancreas, Small Intestine, Large Intestine 4 of 24 What is a catalyst? Something that increases the speed of the reaction without being changed or used up. 5 of 24 What is an enzyme made up of? Proteins which are made up of amino acids. 6 of 24 What goes in the active site of an enzyme? A substrate. 7 of 24 Enzymes can catalyse many different reactions. True or False? False, they have one specific reaction. 8 of 24 What is the diagram that models enzyme reactions? The lock and key diagram. 9 of 24 Why won't enzymes work if they become too hot? The bonds of the enzyme break and the active site will change shape so won't be able to fit the substrate anymore. 10 of 24 How does pH affect an enzyme? If the enzyme is too high or too low then the active site becomes DENATURED. 11 of 24 What do digestive enzymes do? They break down big molecules so they can pass easily through the walls of the digestive system. 12 of 24 What does amylase break down? Starch. 13 of 24 Where is amylase made? Salivary glands, pancreas and small intestine. 14 of 24 What does carbohydrase convert into what? Carbohydrates into sugars. 15 of 24 What does protease convert into what? Proteins into amino acids. 16 of 24 What does lipases convert into what? Lipids into glycerol. 17 of 24 Where is protease made? Stomach, pancreas, small intestine. 18 of 24 What is protease in the stomach called? Pepsin. 19 of 24 Where are lipases made? Pancreas and small intestine. 20 of 24 Where is bile produced? The liver. 21 of 24 Where is bile stored? The gall bladder. 22 of 24 How does bile neutralise the stomach? It is an alkaline so it neutralises the acid of the stomach. 23 of 24 What does 'emulsifying fat' mean? Bile breaks down fat into tiny droplets which gives them a bigger surface area. Making digestion much faster. 24 of 24
