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...

when cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another. What is this process called? - Answer-signal transduction When does signal transduction begin? - Answer-when the receptor on a target cell recieves and incoming extracellular signal and then produces intracellular signaling molecules that alter cell behavior extracellular signal molecules, released locally example: inflammation regulation at site of infe...
