SATHEE: Neural Control and Coordination Question 25

Neural Control and Coordination Question 25

25. In the resting state of the neural membrane, diffusion due to concentration gradients, if allowed, would drive

[2004]

(a) $K^{+}$ into the cell

(b) $K^{+}$ and $N a^{+}$ out of the cell

(d) $N a^{+}$ out of the cell

Show Answer

Answer : c

Hints & Solutions

(c) In a resting state of the neural membrane, $N a^{+}$ concentration is higher on the outer side and $K^{+}$ concentration is more within the cell. This concentration gradient is maintained by voltage gated channels. Hence if diffusion is allowed $N a^{+}$ would enter the cell and $K^{+}$ would leave.
