"WebDec 19, 2015 · In cells, it is very similar. Proton pumps are a special kind of transporter that push hydrogen ions from areas of low concentration to areas with high concentration. Ions moving down a gradient release energy, but when they move up a gradient, it takes energy. Diffusion can then use this gradient to capture energy again, as the ions move downhill.
