CPPS 325 FINAL EXAM QUESTIONS WITH CORRECT ANSWERS 2023/2024 Graded A+. What is the only example of conformational change activation? - Correct Answer-Insulin 
receptor kinase. 
All other RTKs are activated through forms of dimerization. 
What are the two forms of dimerization? - Correct Answer-i) Receptors exist as 
unactivated dimers until ligand binds (Twist theory) 
ii) exist as monomers that are brought together and activated by ligand binding. 
What is the most common method of dimerizatio...
