Smell

Within the nose they are certain things that odor molecules bind to and then send impulses to the brain to identify and store that smell. “Like a semi-truck that ships things to a store.”

This is the idea that odor molecules and olfactory receptors have a specific look to them, it is like a “lock and key”. The odor molecule is the “key” that fits into a specific olfactory receptor “lock” and activates a sensation of a certain smell by the brain.
