Following statements are regarding to V-class ATPases.

A. An organelle lumen or an extracellular space to become acidic, movement of protons must be accompanied by movement of an equal number of anions (e.g., Cl−) in the same direction.

B. An organelle lumen or an extracellular space to become acidic, movement of protons must be accompanied by movement of equal numbers of a different cation in the same direction.

C. An organelle lumen or an extracellular space to become acidic, movement of protons must be accompanied by movement of equal numbers of a different cation in the opposite direction.

D. An organelle lumen or an extracellular space to become acidic, movement of protons must be accompanied by movement of an equal number of anions (e.g., Cl−) in the opposite direction.
