Web21. jun 2024. · Researchers have finally seen how some smell receptors bind to odor molecules. The work yields new insights into one of the most mysterious and versatile senses. Antennae, such as this one from a fly, carry the receptors that give insects the keen powers of scent detection that they need to survive. Olfaction remains one of the least … Webolfactory receptor, also called smell receptor, protein capable of binding odour molecules that plays a central role in the sense of smell (olfaction). These receptors are common …

WebSelect the correct statement about olfaction. Olfactory adaptation is only due to fading of receptor cell response. Olfactory receptors have a high degree of specificity toward a single type of chemical. Substances must be volatile and hydrophobic in order to activate olfactory receptors. Some of the sensation of olfaction is actually one of pain. WebOlfaction, or the sense of smell, is a complex process that involves several physiological structures and processes. It starts with odor molecules that are present in the air we breathe. When we inhale, these odor molecules travel through the nostrils and reach the olfactory epithelium, which is a small patch of tissue located in the upper part ...
