We basically, instead of opening to this side, we now are open to the other side. So this is the inside or this is the outside, this is the inside of the cell. And so in this state we see that now the membrane protein is open to the outside. And so, in the next step, the lactose basically detaches, moves into the cell and by the same exact type of mechanism, then the h basically detaches and moves into the cell. And once both of these two substances leave the internal cavity of that particular protein, it once again undergoes an aversion in which it inverts and forms back this particular structure. And so, once we form back this particular structure, the cycle can basically repeat itself.
