The actual transport of protons by the proton pump is mediated by a transmembrane protein which undergoes a change in its
il63 [147K]

Answer:

The correct answer is A) Conformation.

Explanation:

Proton pumps are usually molecules that are able to change its conformation in order to transport molecules from one side to the other. The amino acid sequence cannot be changed, because it would change completely the function of the protein. For example, the sodium/potassium pump changes its conformation in order to move these molecules from one side of the membrane to the other.
