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.
Examples of organic molecules include sucrose, cellulose, triglycerides, phospholipds, proteins and deoxyribonucleic acid. Organic molecules are defined as molecules that contain carbon and hydrogen. They are typically divided into four main classes: carbohydrates, lipids, proteins and nucleic acids. Continue Reading.
