What are cell receptors called?

transmembrane receptors
Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored, or integral proteins that bind to external ligand molecules. This type of receptor spans the plasma membrane and performs signal transduction, converting an extracellular signal into an intracellular signal.

What are the three main types of signals cells can receive?

Membrane receptors fall into three major classes: G-protein-coupled receptors, ion channel receptors, and enzyme-linked receptors.

What are cell receptors?

Cellular receptors are proteins either inside a cell or on its surface, which receive a signal. In normal physiology, this is a chemical signal where a protein-ligand binds a protein receptor. Typically, a single ligand will have a single receptor to which it can bind and cause a cellular response.

What are examples of cell to cell communication?

These signals can be:

  • Chemical compounds (example: nutrients and toxins)
  • Electrical impulses (example: neurotransmitters inducing electrical signals along nerves)
  • Mechanical stimuli (example: stretching of the stomach to signal you are full)
