And so in this scenario, we no longer have an electric gradient. In the same way, in this case, we no longer have our concentration gradient. Now, if we combine the concentration gradient with the electrical gradient, we get the electrochemical gradient. So the electrochemical gradient basically combines these two different types of gradients. So notice that in this case, we also had a concentration gradient because we have no molecule C on the right side. All the molecules C were on this side.
