Chapter 19.4, Problem 19.9KCP

Interpretation Introduction

Interpretation:

The type of side chain involved in holding the substrate in the active site and the type of chains involved in the catalytic activity of the enzyme has to be given.

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.

The enzyme can acts as a catalyst due to following capabilities given below:

• It can bring substrates and catalytic sites together.
• It gives acidic, basic or other groups required for catalysis.
• For the reaction to occur, enzyme holds substrate at exact distance and in exact orientation.
• It lowers the energy barrier.
