Explore cell signalling with these specialized notes tailored for Year 1 students in the Cells and Development (CELL0007) module at University College London. Immerse yourself in the complexities of cell signaling, navigating the pathways of signaling through ion channels, deciphering the nuances of electrical signaling, and delving into the intricacies of signaling through receptors. Please note that these materials are intended for personal use only and should be used in accordance with academ...

How do cells communicate with eachother and the body? Find out in this summary that depicts all subjects discussed in the lectures of the course. I got an 18/20 by studying this.

What are the 5 well-known enzyme-linked cell surface receptors? 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 Serine/Threonine residues on IC signalling molecules How are RTK and TK A...

van der Waals correct answer: -weakest (short lives) but lots could strengthen the bond -furthest distance -form as a result of hydrophobic interactions -strength depends on the size of the atoms and the distance between them -cannot be closer than the Van der Waals contact distance or else positively charged nuclei will repel each other (energy= 0) Proteins correct answer: main action molecule of the cell (Most chemical processes of the body are carried out by proteins) -classified in...

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...
