Enzymes are colloidal proteins having catalytic properties. Buchner was awarded Nobel Prize for isolating enzyme zymase from yeast. Sumner catalyzes the first enzyme urease from jack beans. Some similarities between enzyme and catalyst -both remain unchanged during the reaction, both are required in minute quantity, both do not initiate any reaction, both are short-lived compounds and both lower the activation energy. Some differences between enzyme and catalyst- enzymes are protein in nature whereas catalyst is minerals, enzymes catalyzed specific reaction whereas catalysts catalyze a large number of reactions, enzymes are very sensitive to PH and temperature whereas categories are less sensitive to PH and temperature. So take this quiz on enzyme and increase your knowledge about it.
