Enzymes

Life is a complex mesh work involving a perfect co-ordination of avast majority of chemical reactions. Some of these rections result in synthsizing large molecules, other in eleaving large molecules and still others either utilize energy or librate energy. All of these reactions would occur very slowly at the low temperature and the atmospheric pressures, the conditions under which living cells carry on thei life processes. But in the living system these reactions proceed extreamly high rates. This is to due to the presence of some specialised substance or Biocatalysts which are synthesized inside the living cells. These biocatalysts are called Enzymes (Gr: En = in; zyme = yeast). The term enzyme was coined by Friedrich Wilhelm Kuhne (1878). Enzymes may be defined as organic substances capable of catalysing specific chemical reactions in the living system.
