Question
Chapter 17.4, Problem 30AYP
Summary Introduction
To analyze:
The cascade effect for the secondary messenger model of hormone action and the amplification nature of the response.
Introduction:
The eukaryotes have a special type of transmembrane receptors that are present in the plasma membrane. These are signaling molecules that interact with a particular type of proteins called G-proteins based on their binding ability with the

Explain the cascade effect for the second-messengermodel of hormone action. Does the second-messengeramplification produce a slow or rapid response?
Explain why polar hormones cannot regulate their target cells without using second messengers. Alsoexplain in a step-by-step manner how cyclic AMP is used as a second messenger in hormone action.
Explain how second messenger molecules work. Why use a second messenger rather than simply relying on a more direct hormone-stimulated transduction mechanism?
