The bonds that basically hold the phospholipids together and the proteins together inside our cell membrane are intermolecular bonds. They're weak bonds, weak electric bonds. They're electric in nature. And that means, because the bonds holding the phospholipids and proteins together are weak, that means they will not remain stationary in place, but rather, they will be found in a constant sideways motion. So our phospholipids and proteins will be in a constant lateral state of motion. So they will be moving sideways, as shown in the following diagram.
