Question

mechanism of enzyme catalysis

Answer 1

The mechanism of enzyme catalysis. In order for a reaction to occur, reactant molecules must contain sufficient energy to cross a potential energy barrier, the activation energy. ... The lower the potential energy barrier to reaction, the more reactants have sufficient energy and, hence, the faster the reaction will occur.

Answer 2

Answer:Protein molecules of high molecular masses are termed as enzymes. Colloidal solutions are formed when these are dissolved in water. These are complex, nitrogenous organic compounds produced by living plants and animals. Enzymes are also called ‘biochemical catalysts’.

Mechanism of enzyme catalysis:

Various cavities are present with characteristic shapes, on the surface of the enzymes. Such cavities possess active groups such as –NH2, −COOH, etc. Complementary shape of the reactant molecules fit into the cavities just like a key fits into a lock. Activated complexes are formed due to this. This complex then decomposes to give the product.

Hence,

Step 1: E + S → ES+

(Activated complex)

Step 2: ES+ → E + P
