Solutions

Expert Solution

This is really a very lengthy question . After that I will try to clear your concept as much as possible.

Signalling means conversion of extracellular signal into intracellular response.

A. GPCR:

b. Receptor tyrosine kinase :

For example epidermal growth factor (EGF) binds the EGFR to activates the tyrosine kinase activity of the EGFR receptor.

Example : RAS- MAP pathway.

c. Steroid hormone receptor:

The three main types of cell surface receptors are ion-channel-coupled receptors, G-protein-coupled receptors, and enzyme-couple receptors. They are all capable of binding extracellular signaling molecules but differ in how they relay that signal across the membrane. How does each type of surface receptor relay signal?
