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

A

`Ca^(2+)` into the cell

B

`K^+` and `Na^+` out of the cell

C

`Na^+` into the cell

D

`Na^+` out of the cell

Text Solution

Verified by Experts

The correct Answer is:
D
The concentration gradients across the resting membrane are maintained by the active transport of ions by the sodium-potassium pump which transports `3 Na^+` outward for `2 K^+` into cell.

Read the given paragraph. In the resting state, the axonal membrane is ___ with more ___ charged ions outside than inside.This unequal distribution of ions is due to (1) the selective permeability of the membrane, which forms an almost impenetrable barrier to _____ and (2) the action of the ____, which pumps _____ Na^(+) out of the neuron for every ____ K^+ brought in. Select the option that correctly fills the blanks in the paragraph.

An object may be regarded to be rest or in motion depending on the frame of reference chosen to view the object. Because of length contraction it would mean that the same rod may have two dfferent lenghts depending on the state of the observe. Is this true ?
