Answer:
Hydrogen ion (H+) pumps work against their concentration gradient and therefore they need energy inputs from sources such as ATP
Explanation:
The hydrogen ion (H+) pumps are proteins that move protons across biological membranes. These pumps use energy in the form of ATP in order to generate a proton gradient on one side of the membrane. For example, in plants, H+ pump ATPases are able to generate an electrochemical gradient in the plasma membrane. In this case, the proton gradient is employed to drive secondary transport processes, thereby enabling the uptake of diferent metabolites such as nutrients, sugars, amino acids, etc., from the extracellular space.
