Resting membrane potential is maintained by

A

hormones

B

neurotransmitters

C

ion pumps

D

None of these

Text Solution

Verified by Experts

The ionic gradients across the resting membrane are maintained by the active transport of ions by the sodium-potassium pumps (or ion pumps) which transport `3 Na^(+)` outward for every `2K^(+)` into the cell.

In an experiment to measure the membrane potential of a living plant cell micro-electrodes are placed inside and outside the cell. The membrane potential is measured to be 120 mV and a current of 1.5 nA flows through the membrane .Assume that the current density in the cell is uniform. The total area of the cell membrane is 2.0 m m^(2) and its thickness is 12 mum . (a) What is the current density in the membrane? (b) What is the resistivity of the membrane ?

When some potential differece is maintained between A and B, current I enters the network at A and leaves at B

Na^+ - K^+ pump is found in membranes of many cells like nerve cells. It works against electrochemical gradient and involves an integral protein ATPase. At the cost of one ATP, ionic gradient across the resting member is maintained by Na^+ - K^+ pump by transporting
