Chapter 19, Problem 19.85CP

Interpretation Introduction

Interpretation:

The activation energy needed for an enzyme mediated reaction has the same, more or less energy should be determined and the reason should 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.
• Decreases the time required for the reaction by lowering its activation energy.

Activation energy: The energy absorbed by the reactants to break the bond and activation energy can be lowered by enzyme which acts as a catalyst.

The rate of reaction increases if the activation energy decreases.
