Question

Question 6 3 pts Below is a curve show lipid bilayer fluidity that contains mostly saturated triacylglcerides. The x-axis is temperature in C and the y-axis is degree of fluidity (higher value means the membrane is more fluid). I_ I_V_ I I_ __ 4 ó ś io 12 Describe a new curve showing the original bilayer if it had cholesterol added. At low temperature (2) there is less fluidity and at high temperature (12) more fluidity At low temperature (2) there is more fluidity and at high temperature (12) less fluidity At both low and high temperature there is less fluidity At both low and high temperature there is more fluidity Auction 7

Answer 1

Option B is correct

Cholesterol regulates membrane fluidity at both high and low temperature. It increases membrane fluidity at low temperature and at high temperature it decreases membrane fluidity. So it acts as a buffer to maintain membrane fluidity.
