We are able to discriminate possibly 1 trillion odors because each odor activates a characteristic combination of different types of receptors. A specific combination of receptors produces a specific response.
The olfactory receptors are specific proteins that bind odor molecules during the process of olfaction.
These receptors (olfactory receptors) are found in the back of the nasal cavity, where they form the olfactory epithelium.
The olfactory receptors can activate different signaling pathways that lead to the recognition of diverse odors by the brain.
