ENZYMES Enzyme, a substance that acts as a Catalyst in living organisms, regulating the rate at which chemical reactions proceed without itself being altered in the process. The biological processes that occur within all living organisms are chemical reactions, and most are regulated by enzymes. Without enzymes, many of these reactions would not take place … Read more
The Rate of a Chemical Reaction The rate of a chemical reaction can be defined as the amount of the reaction which occurs in unit time. The rate of a reaction is measured by choosing certain properties of the reaction which will indicate how far the reaction has gone, and whose magnitude can be observed … Read more
Catalyst Catalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. ENZYMES are naturally occurring catalysts responsible for many essential biochemical reactions. Most solid catalysts are metals or the oxides, sulfides, and halides of metallic Elements and of the semimetallic elements boron, aluminum, and silicon. Gaseous and liquid catalysts … Read more
