B2, Proteins and enzymes 0.0 / 5 ? BiologyEnzymes and digestionGCSEAQA Created by: emmajane_Created on: 10-04-14 12:14 What are amino acids? Proteins made from long chains of smaller molecules called amino acids 1 of 25 What are long chains folded into? particular shape 2 of 25 What are amino acids important for? Important in relation to how antibodies and enzymes work 3 of 25 How can enzymes be described and what are they? As biological catalysts and proteins 4 of 25 What ensures that enzyme activity is at its greatest? pH and temperature 5 of 25 What happens if the shape of an enzyme chnges? It's denatured 6 of 25 What are proteins? Polymers 7 of 25 What are monomers also called? Amino acids 8 of 25 What do lots of amino acids equal? A protein molecule 9 of 25 Name 4 different types of proteins structural components, hormones, antibodies and enzymes 10 of 25 Why are enzymes folded into smaller shapes? To allow molecules to fit into them 11 of 25 What is the place where enzymes and molecules subtrate called? The active site 12 of 25 What is the optimin pH of intestinal enzymes and stomach enzymes? Intestinal= 7.5 and stomach=2 13 of 25 Name 3 types of enzymes amylase, protease amd lipase 14 of 25 What is the reaction catalysed of amylase and name 3 places where is it produced? starch to sugar and produced in the salivary glands, pancreas and small intestine 15 of 25 What is the reaction catalysed of protease and name 3 places where is it produced? starch to sugars and produced in the stomach pancreas and small intestine 16 of 25 What is the reaction catalysed of lipase and name 2 places where is it produced? lipids to fatty acids and glyserol and produced in thr pancreas and small intestine 17 of 25 What type of acid does the stomach produce and what 2 things does it aid? hydrochloric acid and helps begin digestion and kills harmful microorganisms that might me slallowed with food 18 of 25 What type of pH do enzymes in the small intestine work best at? An alkaline pH 19 of 25 What is the purpose of bile and where is it sproduced and stored? It neutralises acid from stomach before reaching small intestine and is produced in the liver and stored in the gall bladder 20 of 25 How can protease be used in the industry? To pre-digest proteins for baby food 21 of 25 How can lipase be used in the industry? It breakes down substances in stains into smaller, water soluble substances 22 of 25 How can carbohydrase be used in the industry? Converts starch syrup into sugar syrup. Used in sports drinks 23 of 25 How can isomerase be used in the industry? Converts glucose syrup into fructose syrup. Used in dietary products 24 of 25 Why are enzymes expensive to produce in the industry? Because ensymes are denatured at high temperatures 25 of 25
