The light-stimulated proton pump of Halobacterium salinarum indirectly functions to pump sodium out of the cell by the activity of a Na⁺/H⁺ antiport system.

Question

Quizplus · Accepted Answer

The proton pump of Halobacterium salinarum indirectly pumps sodium out of the cell by the activity of a Na⁺/H⁺ antiport system. This system uses the energy from the proton gradient generated by the proton pump to transport sodium ions out of the cell, thereby maintaining the electrochemical balance across the membrane.
