BIOCATALYSIS - LEARN BIO WITH EASE

DEFINE ENZYME

• It sped up rate of biological reaction by lowering the activation energy and remain unchanged at the end of the reactions.

• Speed up rate of reaction

• It boost reactions

• it slow down rate of biological reaction by increasing the activation energy and remain changed at the end of the reactions.

DEFINE INDUCED FIT

• Change in the core of enzyme’s active site

• Change in the conformation of enzyme’s active site, which is induced by the binding of substrate to the active site to suit the substrate’s shape, therefore enhancing interaction and catalysis

• Change in the substrate shape

Select the correct answer, PROPERTIES OF ENZYME 

• All enzymes are globular protein

• Required in small amount to catalyse the reaction

• Enzyme can be denatured by extreme pH/high temperature 

• Enzymes reactions is very sluggish

Define COFACTORS....

• Any non-protein molecule or ion that is required for the proper functioning of an enzyme 

• Any protein molecule or ion that is required for the proper functioning of an enzyme 

• All protein and non-protein molecule or ion that is required for the proper functioning of an enzyme 

Which of them are the Cofactor of Enzyme

• METAL ION ACTIVATORS

• PROSTHETIC GROUP 

• COENZYME

• INHIBITORS
