Degradation Reactions( breakdown ) Metabolism I am the name given to a substance that increases the rate of a chemical reaction but remains unchanged at the end Competitive Inhibitor I am the word used to describe what happens to an enzyme at temperatures above 40°c Enzyme I am the reason why a competitive Inhibitor slows down the rate of reaction Enzyme-Substrate Complex I am the type of enzyme that controls a chemical process inside cells Substrate I am the name given to reactions where enzymes are used to build up complex molecules from smaller ones Protein I am the word used to describe the fact that only one enzyme fits one substrate I am the type of protein that most enzymes are made from although some may be conjugated protein Cyanide and Heavy Metals like Copper, Mercury and Lead I am the word used to describe the best set of conditions that an enzyme works at Denatured Synthesis Reactions(Building Up) I am what affects the degree of inhibition of an enzyme by a competitive inhibitor Specific I am the name given to reactions where enzymes are used to break down complex molecules to smaller ones Catalyst I am the name given to the complex that forms when an enzyme locks with its substrate at the active site Intracellular Enzyme I am the name given to a biological catalyst which speeds up the rate of biochemical reactions Neutral pH (pH7) I am the type of enzyme that controls reactions outside the cell I am the enzyme that works best in acidic conditions (pH2.5) in the stomach to breakdown protein Globular Protein Rate of Reaction Increases I am what happens to the rate of reaction if the concentration of substrate is limited Pepsin I am what happens to the rate of reaction if the concentration of enzyme increases Active Site I am the name given to the area on an enzyme whose shape is determined by the type of bonding between amino acids in the polypeptide chain that make up the enzyme Optimum I am the pH at which most enzymes operate Extracellular Enzyme I am the name given to the substance that an enzyme acts on Competitive Inhibitor and Non-Competitive Inhibitor I am the inhibitor that competes with the substrate for the active sites on an enzyme as it has a molecular structure similar to the substrate Water and Oxygen I am the test for oxygen gas Inhibitor I am the two types of inhibitor Non-Competitive Inhibitor I am four examples of non-competitive inhibitors I am the substance that enzymes are made from The Rate of Reaction Decreases I am an enzyme made in living cells to breakdown hydrogen peroxide Relights a Glowing Splint I am the name given to a substance which decreases the rate of an enzyme-controlled reaction and may even bring it to a halt Catalase I am the two products formed from the breakdown of hydrogen peroxide The Active Sites Become Blocked by the Competitive Inhibitor and the Substrate can no longer fill these spaces Concentration of Inhibitor Only I am the type of inhibitor that combines with an area away from the active site and indirectly alters the active site so it no longer fits the usual substrate Co-factor I am the name of an inhibitor that can affect the action of catalase enzyme on its substrate hydrogen peroxide Copper Nitrate I am the name given to co-factors that contain vitamins as the main part of their molecular structure Concentration of Inhibitor and Substrate I am the name given to a non-protein substance like zinc, iron, copper or magnesium that must be present to activate an enzyme Enzyme Activators I am what affects the degree of inhibition of an enzyme by a non-competitive inhibitor I am the name given to a group of chemical processes that occur in the human body to keep it alive I am the name given to substances that convert an inactive enzyme to an active form e.g. trypsin converts inactive chymotrypsinogen to active chymotrypsin to digest protein in the small intestine Co-Enzymes
