An Intro to Receptors - Types, Structure & Location - Part 1

Dive into a comprehensive 55-minute lecture on receptor biology, exploring their types, structures, and locations. Learn about sensory receptors and their roles in physiology, biochemistry, and pharmacology. Understand the definition of receptors and their various locations within cells. Explore transmembrane receptors, with a focus on G-protein coupled receptors (GPCRs) and their mechanisms. Discover intracellular receptors, including cytosolic and nuclear types, as well as extracellular receptors like antithrombin III. Gain insights into the mechanism of action of heparin and its interaction with receptors. Conclude with a summary of key concepts and a preview of upcoming topics in receptor biology.
