Question

What is the mechanism of enzyme catalysis

Answer 1

Ello user !!!!!!!

Here is your answer,

===============================================

Enzymes can catalyze reactions through a variety of mechanisms.

Some of these include:

Bond strain: enzymes can destabilize bonds within the substrate.

Proximity and orientation: conformational changes in the enzyme upon substrate binding can bring reactive groups closer together or orient them so they can react.

HOPE THIS HELPS YOUU :)

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
