Question

and D. Allows you to calculate the equilibrium potential for an on, besed only on she concetration of the ion IS. In intracellular recording, the potential is measured. A. B. C. D. Between the soma and the initial segment Across the synapse. Across the cell membrane. Along the length of the axon. 16. In most neurons, the [K "l is about 10 tim es as great as its external concentration. If one then doubled the (k lo around such a neuron, the membrane potential would: A. Stay the same. B. Go to zero. C. Move toward zero, but not reach it. D. Move away from zero. 17. The action potential is governed, respectively, by the entry and exit of A. Na" and Ca B. Na and K C. K and Ca D. Na and Cr E. K and Cl. I8. Excitable cells are different from non-excitable cells by Excitable cells have membrane potentials, whereas Non-excitable cells have membrane potentials whereas Excitable cells generate an action potential at threshold-level stimuli, whereas non-excitable A. non-excitable cells don't B. C. cells don't D. Non-excitable cells generate an action potential at threshold-level stimuli, whereas excitable cells don't

Explanation / Answer

Ans 13 : A) Na+ battery , because Na+ drives the action potential

The neuron or the nerve cell is called as the sodium battery as it holds in a charge always. The intake of Na+ ions take place while the depolarisation as the membrane potential changes.
