National 4/5 Biology Unit 1 – Proteins and Enzymes – WORDBANK region on an enzyme molecule to which the substrate molecule becomes attached during the reaction enzyme made by plant and animal cells that promotes the breakdown of starch to maltose chemical reagent used to test for simple sugars enzyme that promotes the breakdown of hydrogen peroxide to oxygen and water chemical that increases the rate of a chemical reaction and remains unaltered copy of an experiment in which all factors are kept exactly the same except the one being investigated in the original experiment term used to describe the state of an enzyme that has lost its activity e.g. due to excess heat chemical breakdown of large complex molecules to simpler ones substance formed as a result of an enzyme acting on its substrate protein made by living cells that acts as a biological catalyst term used to describe the condition at which an enzyme works best enzyme present in potato cells that promotes the synthesis of starch from glucose-1-phosphate substance upon which an enzyme acts building-up of large complex molecules from simpler ones by an enzyme-controlled reactions Chemical reagent used to test for presence of starch Cleaning agent which contains enzymes Enzyme containing substance used in the production of cheese Complete the word bank using the following words: Enzyme, Catalyst, Catalase, Amylase, Phosphorylase, Substrate, Product, Iodine solution, Benedict’s solution, Control, Optimum, Active site, Denatured, Biological detergent, Rennet, Degradation, Synthesis
