CPPS 325 FINAL EXAM WITH 100% CORRECT ANSWERS 2023/2024 Graded A+. 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. Receptor Tyrosine Phosphates: Removes phosphate on tyrosine residues 5. Receptor Serine/Threonine Kinases: phosphorylate specific...

why do specimens need to be thin when observing them under a light microscope? - to allow light to pass through identify and explain the starch test - add iodine dissolved in potassium iodide solution to the sample - positive test = blue-black - negative test = orange-brown why is the structure of the plasma membrane often referred to as the fluid mosaic model? - - the continuous bilayer is 'fluid' as the phospholipid molecules are constantly moving - protein molecules are scattered thr...

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...

what did multicellularity lead to? - need for a highly coordinated system to regulate and integrate the physiological functioning of different cells within one organism mode of hormonal communication? - chemical signalling examples of types on triggers? - location, visual, language, sound, gesture visual trigger - circadian rhythms location trigger - sender to receiver language trigger - chemical signalling gesture trigger - social, stress, sex sound trigger - lactation what is the unit...

Topic 1 Introduction to Molecular Cloning 1. The goal of this integrated practical course is to purify a protein. In general, what is the value of protein purification to medical research? What information can a purified protein provide and what techniques can be developed/employed once you have a purified protein?  In vitro studies - Small molecule interactions, protein binding partners etc  Producing antibodies  Determination of structure Purification of the protein is a valua...

This document contains the signalling pathways you should be able to draw on the exam. I made these based on the things seen in class and articles. I had maximun on this question on the exam (10/10)!

types of lipids (purpose) correct answer: storage, structural, and signalling fatty acid chemical structure and charge correct answer: - fatty part is the carbon chain - acid part is carboxyl group (-COOH) - negatively charged which conformations of saturated fatty acids are most stable? correct answer: - anti conformation - extended conformation unsaturated fatty acids correct answer: double bonds are almost always in cis conformation which results in kinks in structure mono-...

Psychology Year 11 Final ATAR Exam Questions & Answers 2024/25 Alzheimer's - ANSWERSdegenerative brain disorder that gradually destroys memory and cognitive functioning Cause build-up of beta amyloid plaques and tangles of tau protein. They combine to disintegrate the brain structure, by blocking nerve signalling and communications between cells and also by triggering immune system reactions, which destroy disabled nerve cells. Form in the hippocampus (temporal lobe)= short term mem...
