Define the term biological catalyst
WebA substance able to increase the rate of a chemical reaction without itself being consumed or changed by the reacting chemicals is called a catalyst. The action of a catalyst is called catalysis. Catalysts are used by chemists to speed up chemical reactions that otherwise would be inconveniently slow. The exact mechanisms of catalytic actions ... Webamylase, any member of a class of enzymes that catalyze the hydrolysis (splitting of a compound by addition of a water molecule) of starch into smaller carbohydrate molecules such as maltose (a molecule composed of two glucose molecules). Three categories of amylases, denoted alpha, beta, and gamma, differ in the way they attack the bonds of …
