Chapter 8, Problem 5Q

Summary Introduction

To review:

The property of an enzyme in general, which enables luciferase to attach only to luciferin molecule. Also, explain catalysis by luciferase taking this enzymatic property into consideration.

Introduction:

The fireflies show the phenomenon of bioluminescence with the help of luciferin, which is present in their abdomen in an organ known as a lantern. This reaction takes place in the presence of an enzyme luciferase, which behaves as a catalyst.

The enzyme luciferase undergoes a change in the shape when it binds to luciferin and adenosine triphosphate (ATP). This prevents the attachment of the water molecule at the active site of the enzyme.
