Question

Principal of working of enzyme

Answer 1

Enzymes are organic catalysts that are important to all living things due to the continuous-controlled chemical activities in cells. Enzymes regulate metabolism by altering the rate of chemical reactions. Activation energy is decreased in order to alter chemical reaction rates. In addition, enzymes are able to transform one form of energy to another. Due to the fact that enzymes are highly selective, they may only catalyze one or a specific class of reactions. The place where an enzyme binds onto the substrate is called an active site. A substrate is the molecule that enzyme acts upon.

There are two theories that describe the binding of enzymes: 1) Lock and Key Theory and 2) Induced Fit Theory.

1) Lock and Key Theory: The shape of the enzyme's active site is complementary to that of its substrate

2) Induced Fit Theory: The active site has a flexibility of shape, thus when an appropriate substrate comes in contact with the enzyme's active site, the shape of the active site would change to fit with the substrate.
