Interpretation Introduction

Interpretation:

The definition for zymogen and the reason why some enzyme is secreted as zymogen should be determined.

Concept introduction:

Enzyme:

• It is a protein or a molecule which can act as a catalyst for a biological reaction.
• Does not affect the equilibrium point of the reaction.
• Active site of the enzyme is the region where the reaction takes place.
• Enzyme’s activity can be specific which means the activity is limited to a certain substrate and a certain type of reaction and it is referred to as specificity of the enzyme.

Enzyme regulation:

Some enzymes can destroy the organ in which they are produced and they are often synthesized as proenzymes or zymogens.
