Answer:
Energy
Explanation:
Usually the inside of the cells is hypertonic to the extracellular matrix. This means there are more ions in the cell than outside. Therefore the cell requires energy to pump more ions into the cell against the concentration gradient. The sodium-potassium pump utilizes energy from ATP to pump Na+ and K+ ions 'uphill' into the cell.
The answer is C. Cell wall is directly outside of the cell membrane.
Cell walls allow substances to pass through regularly but transport in and out of the cell is still regulated by the cell's membrane.
