Absolute specificity means that one and only one substrate will fit with a particular enzyme. The enzymes activity is greater around pH of 8.0 . Why are enzymes specific in their action? called the substrtate. Specific enzyme activity (usually stated simply as 'specific activity') is the number of enzyme units per ml divided by the concentration of protein in mg/ml. It is the opposite of narrow substrate specificity. What is specificity in relation to enzymes? Enzymes are highly specific catalysts for biochemical reactions, with each enzyme showing a selectivity for a single reactant, or substrate. For instance, in ancient Egypt, breads and beer were produced by rudimentary fermentation techniques through mere experimentation and primarily for preservation purposes. What is meant by specific activity? The example for this type of specificity is hexokinase phosphorylating one or more kind of hexoses which include glucose, mannose fructose etc. The enzyme protease (which breaks peptide bonds in proteins) will not work on starch (which is broken down by an enzyme amylase). : the quality or condition of being specific: such as. Enzymes are also substrate specific. The restriction endonucleases have exquisite specificity and fall into this first category. Enzyme specificity describes the tendency of an enzyme to catalyze a specify biochemical reaction by binding to specific substrate. Relative specificity is defined as the characteristic whereby in a biochemical system, a molecule, symbolized as E, interacts with its numerous substrates, targets or partners (collectively symbolized as {S}) differentially, thereby impacting them distinctively depending on the identity of individual substrates, . These are enzymes that facilitate the removal of small molecule from a large substrate e.g., fumarase, argino succinase, histidine decarboxylase.
