And so the membrane will be more rigid. And so we see that the stronger the interactions between the molecules in the membrane, the stronger these intermolecular bonds are, the more rigid the membrane is. And conversely, the weaker the interactions are, the less rigid and more fluid that membrane actually is. So let's take a look at the following graph. And let's imagine what happens to a membrane as we go from a low temperature to a high temperature. So as we increase the temperature of the environment in which the membrane is in, so the y axis is the fluidity of the membrane.
