And that happens to be in the same direction as the purple arrow. So basically what it does is it allows. So this Simporter, also known as a co transporter, allows the spontaneous movement of these purple molecules down the electrochemical gradient that releases free energy. That free energy is captured by this importer and it is used to move these orange molecules against electrochemical gradient from a low to a high concentration, from the outside to the inside in the same direction. And so that's why we call them co transporters, simporters. In this case, they're called anti porters or exchangers, because they move in opposite directions.
