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. WebThe Sucrose Loading Mechanism. Assimilates such as sucrose are transported from source to sink through the phloem sieve tubes.
