Investigate the effect of temperature on dehydrogenase activity in yeast. At which temperature is tetrazolium chloride (TTC) discoloured most rapidly? Introduction Enzymes are composed of many specialised organic substances, such as polymers of amino acids, which act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms. Individual enzymes are naming by adding -ase to the name of the substrate with which they react. There are many types of enzymes such as... hydrolytic, oxidising, and reducing. * Hydrolytic... speed up reactions in which a substance is broken into simpler compounds through reaction with water molecules. * Oxidases... these are oxidising enzymes that speed oxidation reactions. * Reductases... reducing enzymes that accelerate reduction reactions. "Enzymes are highly specific in their actions. Each enzyme catalyses either a single chemical reaction or a group of closely related reactions" Enzymes operate by attaching themselves to their substrate molecule at the active site. The...
