Enzymes

Enzymes are biocatalyst.

Catalyst means increase the velocity or rate of chemical reaction without itself undergoing any change in overall process.

Enzymes is protein that is synthesized in a living cell.

Enzymes absence in chemical reaction then it is slow process of reaction.

Enzymes are sensitive to temperature.

Also sensitive to PH.

All protein is not enzymes.

All enzymes are protein.

Holoenzyme

Completely catalytic active in Enzyme.

Holoenzyme is apoenzyme + cofactor.

Holoenzyme is active

Apoenzyme is inactive

Cofactor is inactive.

Cofactor

Non proteins component of the enzyme.

Cofactor can be classified into three groups

Coenzyme

prosthetic group and 

metals ions.
