Question

What are enzymes ?Give two examples with uses.

Answer 1

Enzymes are complicated organic molecules which are produced by living cells and are also called biological catalysts. They are complex nitrogenous molecules, unlike energanic catalysts, they take part in the reaction and get destroyed.
Factors affecting the activity of catalyst ;
(i) Temperature, (ii) pH, (iii) concentration of enzyme, (iv) concentration of substance, (V) concentration of the product formed.
Functions of Enzymes : Enzymes play a very important role in many biological reactions. They names of some important enzymes and the biochemical reactions catalysed by them are given below :
(1) Role of enzymes in the process of digestion : Enzymes play an important role in digestionresulting in breakdown of macro molecules into simple molecules.
(2) Industrial application : Enzymes play an important role in many industrial processes such as manufacture of ethanol from sugar or starch, manufacture of acetic acid, manufacture of cheese, leather, tanning etc.
