Explain role of mineral salt in creation of electric tension, Biology

Assignment Help:

What is the role of mineral salts in the creation of electric tension (voltage) at the cellular level?

The electric activity of the cell, for instance, in neurons, depends on the different concentrations of positive and negative ions among the inner and the outer surfaces of the cell membrane. Mineral salts are responsible for that voltage.

The cell membrane of non-excited cell has commonly a negative inner side and a positive outer side. This electrical situation is maintained by ion transport across the membrane.
