If you’re nervous before a test or competition, your adrenal gland is likely to be pumping out epinephrine. When epinephrine binds to its receptor on a muscle cell (a type of G protein …

Learn how signals are relayed inside a cell starting from the cell membrane receptor. The chains of molecules that relay intracellular signals are known as intracellular signal transduction …

Posted 3 years ago. Direct link to Wassim Khan's post “what is signaling by cell...”

Transduction In transduction, viruses that infect bacteria move short pieces of chromosomal DNA from one bacterium to another "by accident." Yep, even bacteria can get a virus! The viruses …

Types of signaling molecules and the receptors they bind to on target cells. Intracellular receptors, ligand-gated ion channels, G protein-coupled receptors, and receptor tyrosine kinases.

Explore how alterations in signal transduction pathways affect cellular communication. Understand the role of G protein-coupled receptors in initiating responses.

Hi, this isn't mentioned in this article, but I would like to ask, What is the difference between a gene and a cistron? Why do we need the term , cistron, in the first place? And what do the …

I'm still a little confused but what is the purpose of G protein receptors specifically? Like what can they do that is unique to the other receptors?

Signal transduction is a complex process where cells communicate through chemical signals. This involves a ligand binding to a receptor, initiating a cascade of events that can alter cell behavior.
