Now, the next question is what exactly are the details of the mechanism by which this process actually takes place? So it's slightly different than the process in the ptype Atpas, and let's see exactly what it actually looks like. And of course, I forgot to finish off one of these membranes, so let's do it real quick. So we have the polar heads, and so some of you basically ask why I don't actually draw as I go along in the lecture. And that's because it takes up lots and lots of time and that's time that you don't want to lose. So I basically create these diagrams and write my notes ahead of time to basically save your time so that the lecture is as effective and efficient as possible so that you can get the information out as quickly as possible and go on with your lives.
