In general, colder temperatures reduce the fluidity of the membrane, so cells will produce different molecules to maintain the proper degree of fluidity. How would the membrane change in response to colder temperatures?

Question

Quizplus · Accepted Answer

In response to colder temperatures, the membrane would increase the amount of unsaturated fatty acids. This is because unsaturated fatty acids have kinks in their tails due to double bonds, which prevent them from packing tightly together. This results in a more fluid membrane that is better able to function in colder temperatures.
