Many different cell surface receptors couple to and interact with specific subtypes of G proteins. All G proteins are heterotrimers

However, some reports indicate that rats or hamsters with LOT transection are anosmic or have severe olfactory deficits (Cattarelli, 1982; Devor, 1973; Long and Tapp, 1970; Marques, O’Connell, Benimoff, and Macride

On the other hand, it has been shown that nonolfactory systems such as the turtle trigeminal nerve (Tucker, 1963), the . ganglion, the fly taste nerve, the frog taste cell, and the neuroblastoma cell respond to various odorants (Kashiwayanagi et al., 1984; 1985). These nonolf
