Introduction In the human body, hormones such as insulin and growth hormones interact with cells by enzyme-linked receptors to induce a process inside the cell. An enzyme-linked receptor is a transmembrane protein that responds to signals using an extracellular ligand-binding domain that is linked to a cytoplasmic enzymatic catalytic activity site (Dowd, F. J., & Abel, P. W. (2017). Pharmacodynamics. Pharmacology and Therapeutics for Dentistry, 2–14. https://doi.org/10.1016/b978-0-323-39307-2.00001-1). This means…

In the last article we looked at G-protein coupled receptors. Now, we will be going over the another main type of cell receptors: ion channel receptors. [A 3D model of ion channels] (March 19th 202) https://www.drugtargetreview.com/news/57643/ion-channel-ball-and-chain-mechanism-imaged-after-decades-of-attempts/ Introduction Ligand-gated ion channel (LGICs) receptors are found especially in excitable cells, and are responsible for changing the potential gradient (the difference of charges between intracellular and extracellular spaces). Excitable cells are cells…

[3D concept art of G-protein coupled receptors] (April 27, 2019) https://theskepticalchemist.com/gpcrs-drug-discovery/ Introduction Cell signaling is the communication of cells by releasing, receiving, and responding to chemical signals. (Libretexts, & Harris, K. (2020, July 14). Signal Transduction. Biology LibreTexts. https://bio.libretexts.org/Learning_Objects/Worksheets/Biology_Tutorials/Signal_Transduction) By emitting molecules into extracellular space, cells give out information and commands that are essential for the survival of our cells and body, such as cell proliferation. Cells can give…
