Define enzyme. Describe factors affecting enzyme actions in vivo and vitro

Definition:

Enzymes are biocatalyst produced by living cells to catalyze biochemical reactions.

Properties of enzyme:

·        Protein in nature

·        Colloidal and nondialyzable

·        Heat labile

·        Acts as catalyst

·        Water soluble

·        Have definitive isoelectric p^H.

Factors affecting enzyme activity:

·        Temperature

·        P^H

·        Substrate concentration

·        Enzyme concentration

·        Product concentration
