Question
A turkey ordorant molecule comes in contact with the pie ordorant receptor. Would this have an effect on the nerve stimulus being sent from this olfactory cell? Which G protein is activated in this pathway?
Consider the following signal transduction pathway (figure below) involved in smelling apple pie. 1) An apple pie odorant molecule (л), one of the many aromatic compounds present in apple pie, binds to a specific G protein-coupled olfactory receptor in an olfactory cell in your nose. 2) The receptor-odorant complex activates a G protein, which displaces GDP and then binds to a molecule of GTP. 3) The a subunit of the G protein dissociates and activates adenylate cyclase, which catalyzes the production of cAMP from ATP. 4) CAMP binds to a sodium channel, opening it and allowing Na+ to enter the cell. This creates a nerve stimulus, which travels to the brain. The brain interprets the signal as the odor of apple pie. You think, "Mmm...pie." лodorant receptor adenylate cyclase sodium channel 1) 4) ATP GTP √6/7 a GDP a GTP 3) CAMP Na+
