Question

How does a catalyst influence a chemical reaction?

Answer 1

Enzymes are the specific class of catalyst that has an ability to speed up the chemical reaction. They are protein in nature that can bind to reactants at a specific site called the active site.

Further Explanation:

Catalyst is the enzyme that catalyst that has an ability to speed up the chemical reaction. It performs specific functions in an individual body. It helps in speeding up the rate of chemical reactions inside and outside the cell. It has two fundamental properties; they don't get consumed during the chemical reaction. It does not alter the chemical equilibrium between reactants and products.

They bind to the substrate at the active site which is a very specific interaction. Active sites usually have grooves on the surface which is composed of amino acid. These amino acids consist of different parts of the polypeptide chain that are brought together by the tertiary structure of the folded protein.  

Initially, the substrate binds to the active site by noncovalent interactions. Once the substrate binds to the active site of an enzyme, a number of mechanisms can speed up its conversion to the product of the reaction

Answer 2

Answer:

A catalyst is a substance used for speeding up the chemical reaction. In addition, it is never consumed in a reaction and is required in a small quantity.

A catalyst increases the rate of chemical reaction by decreasing its activation energy.

Common types of catalysts are enzymes, acid-base catalyst etc.
