Unit 4 Human Biology - Enzymes 0.0 / 5 ? Applied ScienceEnzymes. BTEC NationalAQA Created by: Hannah Marie WilliamsonCreated on: 05-04-19 15:36 What are enzymes? Protein molecules and are made up of amino acids. Most enzymes contain between 100 and 1,000 amino acids. 1 of 7 How are these amino acids joined together? In a long chain which is folded to produce a unique 3D structure. 2 of 7 Why is shape important? It has a direct effect on how it catalyses a reaction. 3 of 7 How is the shape determined? By the order of amino acids in its structure and the bonds which form between the atoms of those molecules. 4 of 7 Why do different types of enzymes have different shapes and functions? The order and type of amino acids in their structure is different. 5 of 7 Why are enzymes very specific about which reactions they catalyse? Only molecules with exactly the right shape will bind to the enzyme and react. These are the reactant and substrate molecules. 6 of 7 What is part of the enzyme to which the reactant binds? The active site, it is a specific shape and is the important part of the enzyme. 7 of 7
