CPPS 325 FINAL EXAM With Updated &Verified Answers 2023/2024 What are the 5 well-known enzyme-linked cell surface receptors? Correct Answer 1. Receptor Guanylyl Cyclase: produces cGMP 2. RTK: phosphorylate tyrosine residues leading to association of signalling molecules and cascade 3. TK Associated Receptors: associate with proteins having TK activity 4.

CPPS 325 FINAL EXAM QUESTIONS AND COMPLETE SOLUTIONS

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...

CPPS 325 FINAL EXAM QUESTIONS WITH COMPLETE SOLUTIONS What is src? - Answer-Src is a non-receptor TK, so it does not span a membrane. It is a tyrosine kinase. And although it is cytoplasmic TK it can still bind to activated RTKs. What is contact inhibition confluency? - Answer-Stops Src domains signalling and therefore cells stop dividing. If there is an issue then cancer can result and mutation causes an inhibition of the stop signal so the cells keep growing and dividing. What are...

CPPS 325 FINAL EXAM QUESTIONS WITH COMPLETE SOLUTIONS RTK vs. Serine/Threonine Phosphorylation ? - Answer-Tyrosine phosphorylation is rare (1%) relative to serine/threonine residue phosphorylation. Tyrosine phosphorylation is the major mechanism of receptor signal transduction. What is the net effect of activated TKs? - Answer-Tyrosine phosphorylation on target proteins. What do TK pathways mediate? - Answer-Cell growth (growth factors), differentiation, host defense, metabolic regulati...
