UNC Biol 205 Exam 2 Questions With Verified Answers 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? - answersignal transduction When does signal transduction begin? - answerwhen 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 loca...

CPPS FINAL EXAM Practice Questions WITH CORRECT ANSWERS Graded A+ | 2023/2024. What is the importance of RBD in Raf activation? - Correct Answer-It is the N-terminal regulatory domain of the Raf protein. The RBD needs to interact with RasGTP to enable activaiton of Raf. Interaction of RBD with RasGTP at the membrane destabilizes Raf interaction with 14-3-3. This allows for PP2A to dephosphorylate Raf phosphoserines (the locks on the inactive state). What is RBD? - Correct Answer-Ras Binding...
