These photoreceptors are localised around an area near the centre of the retina called the macula, which is the functional centre of the retina.
WebDiagram of one way that a metabotropic receptor can act. The ligand binds to the receptor, which triggers a signaling cascade inside the cell. ... Alternatively, a neurotransmitter that binds to a metabotropic receptor may change how the cell responds to a second neurotransmitter that acts through a ligand-activated channel. Signaling through ... WebCell-surface receptors are membrane-anchored proteins that bind to ligands on the outside surface of the cell. In this type of signaling, the ligand does not need to cross the plasma membrane. So, many different kinds of molecules (including large, hydrophilic or "water-loving" ones) may act as ligands.
