What is the Role of Proton Pumps in Root Hair

Question

What is the role of proton pumps in root hair cells?
A) establish ATP gradients
B) maintain the H⁺ gradient
C) pressurize xylem transport
D) eliminate excess electrons
E) assist in active uptake of water molecules

Accepted Answer

Proton pumps in root hair cells help to maintain the H⁺ gradient necessary for the active uptake of mineral ions and other nutrients from the soil into the plant. This process is known as proton pumping or proton extrusion.
