What does the receptors do?

Cell receptors, including hormone receptors, are special proteins found within and on the surface of certain cells throughout the body, including breast cells. These receptor proteins are the “eyes” and “ears” of the cells, receiving messages from substances in the bloodstream and then telling the cells what to do.

Herein, what are the 3 types of receptors?

Cell surface receptors fall into three main classes;
  • Ligand-gated ion channel receptors.
  • Enzyme-coupled receptors.
  • G-protein-coupled receptors.

What is the role of the receptor cells?

Receptors are proteins or glycoprotein that bind signaling molecules known as first messengers, or ligands. They can initiate a signaling cascade, or chemical response, that induces cell growth, division, and death or opens membrane channels.

What are the four basic types of receptors?

Broadly, sensory receptors respond to one of four primary stimuli:
  • Chemicals (chemoreceptors)
  • Temperature (thermoreceptors)
  • Pressure (mechanoreceptors)
  • Light (photoreceptors)
