1 The cilia of the sensory neurons are immersed in a layer of mucus. 2  Odorant molecules (molecules that we can smell) dissolve in the mucus and. 3  bind to receptors on the cilia.4  These are 7-pass transmembrane proteins. 5  Binding of the odorant activates a G protein coupled to the receptor on its cytoplasmic side. bind to receptors on the cilia. 2  These are 7-pass transmembrane proteins. 3  Binding of the odorant activates a G protein coupled to the receptor on its cytoplasmic side. 4  This activates adenylyl cyclase, an enzyme embedded in the plasma membrane of the cilia.
If the molecule contains more than one kind of atom, it is called heteroatomic. The presence of homoatomic molecules indicates that not all elements prefer to be in the state of individual atoms. There are elements that are molecular and composed of two, four, or even eight atoms.The most common diatomic molecular elements are Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine. Phosphorus exists as a molecule with four atoms. Sulfur is a ring of eight atoms.f the molecule contains more than one kind of atom, it is called heteroatomic.
