5. Below is a diagram of a plasma membrane protein that functions as a growth factor (GF) receptor When a specific growth factor binds to the extracellular domain of this protein, the receptor protein dimerizes i.e. two polypeptide chains join together to make a dimerized protein. The GF receptor is active following dimerization as shown below. [Total 16 pts] Growth factor Growth factor receptor Extracellular Plasma membrane Cytosol Dimerized receptor protein INACTIVE ACTIVE 5a. What is the highest order of this proteins structure (primary, secondary, tertiary or quaternary) in its inactive state? Explain your choice. [2 pts]
