A large number of chemical reactions will be taking place in a cell. The rate and efficiency with which these reactions go on in a cell, depend on a group of macromolecules called enzymes. Enzymes are thus, biological catalysts. Enzymes are synthesised by li..

Enzymes - Amylase is an enzyme to degrade starch. It is produced from Bacillum subtilis, Bacillus polymya (bacteria) as well as Aspergillus niger, Aspergillus oryzae, Rhizopus oryzae (fungi). Amylase is widely used pharmaceutical, beverage, textile confectionary industries. Prot..

Classification of Enzymes - Enzymes are generally classified on the basis of the type of reactions that they catalyse. 6 groups of enzymes can be recognised on this basis. The following table lists the 6 groups of enzymes along with example. fig. 14.15 - Clas..

Enzymes in general exhibit the following properties Enzymes are basically proteins. They are globular proteins with a very huge molecular weight. For example, the molecular weight of pyruvic dehydrogenase is 4,600,000! Enzymes can only accelerate a chemical reaction. h..

These are enzymes used to extract DNA from a cell for genetic experiments. Lysozyme is commonly used to dissolve the bacterial cell wal..

These enzymes, also called as ligases, help in sealing gaps in DNA fragments joined by complementary base pairing. e.g. Tuligase..

These enzymes play a role in the synthesis of DNA strands on suitable templates. They are of two types, Reverse transcriptases, which help in the synthesis of complementary DNA strands on RNA templates, DNA polymerase, which aid in the synthesis of complementary DNA strands on DNA t..

Enzymes and Inorganic Catalysts - Enzymes resemble inorganic catalysts in several aspects and differ from them in many other features. These similarities and differences are summarised in the following table. fig. 14.12 - Similarities and Differences between Enzymes an..
