PhysioEx 9.0 exercise 3 activity 1 and 2

These question are in PhysioEx 9.0 exercise 3 Activity 1 and 2

Activity 1

3. Explain why a change in extracellulat Na+ did not alter the membrane potential in the resting neuron.

Activity 2

5. The olfactory receptor also contains a membrane protein that recognizes isoamyl acetate and, via several other molecules, transduces the odor stimulus into a receptor potential. Does the Pacinian corpuscle likely have this isoamyl acetate receptor protein? Does the free nreve ending likely have this isoamyl acetate receptor protein?

There are less leakage sodium channels that leakage potassium channels, and more of the potassium channels are open.

The Pacinian corpuscle and the free nerve ending are not likely to have the isoamyl acetate receptor because they did not respond to chemical stimuli.
