Further, it is a transmembrane receptor, an enzyme catalyst, an enzyme-coupled receptors known as catalytic receptor binding of extracellular ligands, enzymatic activity of the catalyst side.Hence receptors in cells, the receptor I make is an integral membrane protein having both functions.
G protein–coupled receptors (GPCRs), also known as seven-(pass)-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein–linked receptors (GPLR), constitute a large protein family of receptors that detect molecules outside the cell and activate internal signal transduction pathways and, ultimately, cellular responses.
G protein-coupled receptor (GPCR), also called seven-transmembrane receptor or heptahelical receptor, protein located in the cell membrane that binds extracellular substances and transmits signals from these substances to an intracellular molecule called a G protein (guanine nucleotide-binding protein).
In neural cells, there are three superfamilies of extracellularly activated ligand-gated ion channel subunits: the receptors of the Cys-loop superfamily (nicotinic receptors, 5-HT3 receptors, GABA-A and GABA-C receptors, glycine receptors, and some glutamate, histamine, and serotonin-activated anionic channels), the ATP-gated channels (ATP2x receptors), and the glutamate-activated cationic channels (NMDA receptors, AMPA receptors, kainate receptors etc.).
A photoreceptor cell is a specialized type of sensory neuron found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes.

A mechanoreceptor is a sensory receptor that responds to mechanical pressure or distortion. Normally there are four main types in glabrous, or hairless, mammalian skin: lamellar corpuscles, tactile corpuscles, Merkel nerve endings, and bulbous corpuscles.
