=From the article "Enzymes That Aid Beverages"= = Q&A = =1. List out the six categories of enzyme.= = Oxidoreductases, hydrolases, lysases, transferases, ligases and isomerases. = = = =2. Describe one of the characteristic of enzyme.= = Most enzymes catalyze highly specific reactions. For example, alpha-amylase (alpha-1-4-glucan glucanhydrolase) attacks the alpha bonds between the glucose portions of starch, resulting in the formation of glucose. Not all enzymes show the same degree of specificity, however. Some proteases, such as papain, hydrolyze random peptide bonds in proteins. = = = =3. What factor affect enzyme activity?= = Temperature, pH, concentration, contact time with the substrate, trace metals, salt and salt ions, and oxidizing agents. = = = =4. What are required to break down any starch present in the fruit?= = Amylase and amyloglucosidase. =
