The first step in DNA replication is to unravel the double helix structure of the DNA molecule. What are Enzymes. Enzymes are proteins that catalyze biochemical reactions by lowering the activation energy necessary to break the chemical bonds in reactants and form new chemical bonds in the products. Digestive enzymes are substances that help you digest your food. This works in animals and plants as well. Pronunciations. Enzyme function is dependent on the binding of a substrate at its active site. Enzymes speed the rate of chemical reactions. Enzymes are responsible for a lot of the work that is going on in cells. The substrate binds to the active site, or the place on the enzyme that actually does the work. 'Synthetase' may be used in place of 'synthase' for enzymes in this class. In living organisms, enzymes work best at certain temperatures and pH values depending on the type of enzyme. Because enzymes are not consumed in the reactions they catalyze and can be used over and over again, only a very small quantity of an enzyme is needed to catalyze a reaction. For homebrewers, we are concerned with the activity of two primary enzymes in beer: alpha- and beta-amylase. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles. 'Ligase' is often used for the common name, but, in a few cases, 'synthase' or 'carboxylase' is used. yes they do The general name that chemists use for a chemical entity that increases the speed of a reaction is a "catalyst.".
