Question
Chapter 13, Problem 13P
Interpretation Introduction
Interpretation:
A mechanism needs to be proposed by which the toxin inhibits the flow of sodium ions through the sodium ion channel.
Concept introduction:
Tetrodotoxin is also known as TTX which act as a toxin to voltage-gated sodium channels. After binding, it blocks the sodium ions flow through the channel.

- True or False. The binding affinity between a peptide agonist and its specific G protein coupled receptor alone determines the sensitivity of a cell to the agonist peptide.arrow_forwardAssighment. Create a diagram which illustrates the typical signalling mechanism of action of each of the four common classes of receptor (e.g. kinase-linked receptors etc.) and possible routes of communication (autocrine etc.). Your diagram should show the specific molecules involved, the mechanisms of signal transduction and indicate the different pathways that are activated. It should include a specific example of a receptor, ligand and signalling pathway for each general class. Include as wide a variety of ligands and modes of action as you can. For each of the examples describe the mechanism of action in the form below. DO NOT use any of the ligand-receptor combinations provide to you in the Learning Materials to date - research and create a diagram for a novel pathway instead!arrow_forwardSignal transduction pathway.
