2. How many distinct chemoreceptors are/basic tastes?
- 10
- 5
- 4
- 3 but they do not correspond to the basic tastes
3. What is the core concept of vibration theory?
- Molecules with the same IR vibrational spectrum should smell similar, same shape diff vibrations smell different. Bond energies determine activation level
- A two-stage theory. Molecules must be the right shape to bond to receptor sites but bond energies determine final activation level.
- Receptor specificity is based on molecular structure. Oderants must have the right shape to activate the receptor, there is a certain receptor for each molecule
4. Is the McClintock effect well supported?
- No, original studies were barely significant and accounting for random sync removes effect. No support from large scale long term. Why?
- Yes, original studies are well replicated in both clinical and natural settings and it is widely accepted knowledge
5. Where do OSN axons project to?
- Glomeruli in the olfactory cleft
- Glomeruli in the somatosensory cortex
- Glomeruli in the olfactory bulb
- Glomeruli in the olfactory epithelium
