Across
- 4. Activated after the receptor changes shape; starts the signaling cascade
- 5. The entire process of turning odorant binding into an electrical signal
- 7. Second messenger that opens ion channels in olfactory neurons
- 8. A chemical molecule that binds to receptors in the nose
- 9. Opens in response to cAMP, letting Na⁺ and Ca²⁺ into the cell
Down
- 1. Enzyme activated by Golf to convert ATP into cAMP
- 2. Protein on the olfactory neuron that detects odorants
- 3. Electrical signal sent to the brain once depolarization is strong enough
- 6. Special G-protein found only in olfactory neurons
