So we have the high concentration of purple outside, a low concentration of purple on the inside, as in this particular case. But now we have a high concentration of these orange ones on the inside and a low concentration of the orange ones on the outside. And because of this reversal, we see that the orange arrow will point in the opposite direction, as with respect to this case. 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.
