The Sodium Level Inside and Outside of a Resting Cell

question 14

Multiple Choice

The sodium level inside and outside of a resting cell is an example of the

• A) kinetic energy of sodium rushing out of a cell down its concentration gradient.
• B) kinetic energy of the large difference in sodium concentration on the inside versus the outside of the cell.
• C) potential energy of a concentration gradient, because sodium is more abundant outside the cell.
• D) potential energy of an electron transport chain, because sodium has an extra electron to donate.
• E) conversion of potential energy to kinetic energy, because sodium can never move across the cell membrane and must move across its surface.
