WebOct 28, 2024 · Intracellular Receptors. In biochemistry and pharmacology, receptors are protein-based chemical structures that receive and transmit signals that can be integrated into biological systems. A ligand is an ion or molecule that binds to a central metal atom to form a coordination complex in coordination chemistry. Webchemoreception, process by which organisms respond to chemical stimuli in their environments that depends primarily on the senses of taste and smell. Chemoreception relies on chemicals that act as signals to regulate cell function, without the chemical necessarily being taken into the cell for metabolic purposes.

• Olfaction: In terrestrial vertebrates, olfaction occurs in the nose. Volatile chemical stimuli enter the nose and eventually reach the olfactory epithelium which houses the chemoreceptor cells known as olfactory sensory neurons often referred to as OSNs. Embedded in the olfactory epithelium are three types of cells: supporting cells, basal cells, and OSNs. While all three types of cells are integral to normal function of the epithelium, only OSN serve as receptor cells, i.e. responding t…
