Resting membrane potential is maintained by
1 hormones
2 ion pumps
3 neurotransmitters
4 None of these
Explanation:
(c) The ionic gradients across the resting membranes are maintained by the active transport of ions by the sodium- potassium pumps which transport $3\text{N}{{\text{a}}^{+}}$ outward for every $2{{\text{K}}^{+}}$into the cell.

The resting potential occurs because
1 of reduced energy production by mitochondria.
2 the action potential depletes transmitter substance.
3 of the different concentrations of ions across the cell.
4 the action potential causes axoplasmic transport back towards the cell body.
Explanation:
(c) The resting potential occurs because of the different concentrations of ions across the cell. The electrical potential difference across the resting plasma membrane is called as the resting potential. In the resting nerve fibres, the cytoplasm just beneath its membrane is electronegative relative to the layer of extracellular fluid just outside the membrane.
