Question

Quizplus · Accepted Answer

Proton pumps in the plant plasma membrane function to create a membrane potential by actively transporting protons (H+) out of the cell. This action establishes a gradient of charge and concentration across the membrane, which is fundamental for various cellular processes, including nutrient uptake and pH regulation.
