The pump, which was embedded in the cell membrane, used ATP (adenosine triphosphate) molecules, the energy currency of the cell, to pump the sodium ions back out of Cellville. At the same time, it pumped potassium ions (K+) from the outside into Cellville. This process was an example of primary active transport, where energy from ATP was directly used to transport molecules against their concentration gradient.
Passive diffusion would cause the plant to lose nutrients to the soil! Instead, root hair cells use active transport to forcefully pull scarce minerals from the soil into the plant against the gradient.
The proton pump was similar to the sodium-potassium pump, but it only pumped protons. By creating a proton gradient, the pump helped to drive other transport processes, such as the uptake of nutrients. This was another example of primary active transport, where ATP energy was used directly to transport molecules against their concentration gradient.
In the microscopic world of cells, nature has a preference for moving things from high to low concentration (a process called ). But what happens when a cell desperately needs a substance that is scarce on its side but abundant on the other?
