Answer:
In order for the sodium motive force to provide useful energy for the cell the organism must contain sodium ion gradient or potential across the membrane.
Explanation:
If the concentration of sodium is high in the inter membrane space than that of matrix then a sodium gradient is generated across the inner mitochondrial membrane.
The transport of sodium ions from inter membrane space to matrix through the sodium ion channel result in the generation of sodium motive force,that is used to provide energy to the cell.
