Question

Save Question 9 (1 point) Dramatic temperature changes can induce membrane remodeling involving changing fatty acid structure in membrane phospholipids. This wa occur during the transition from winter to spring and vice versa. The purpose of remodeling is to maintain a constant level of membrane fuidity in the cell. Which of the following describes the change you would see in the lipid bilayer of the cell membranes of a bear when it comes out of hibernation (choose all that apply)? A) the ratio of long to short fatty acid tails in mentranephospholpids decreases B) the number of phospholipids in the membrane decreases C) the ratio of long to short fatty acid tails in the membrane phospholipids increases D) the number of phospholipids in the membrane increases E) there is an increase in the saturation state ofthe fatty acid tals of memtrane phospholipids F) there, is a decrease n the saturation state of the fatty acid tals of rmemtrane phospholipids

Explanation / Answer

During hibernation, beer faces the low body temperature so when they come out of hibernation their body temperature changes from low to high.

When the body is at low temperature there is an increase in the composition of unsaturated fatty acid to maintain the membrane fluidity. So when beer comes out of hibernation membrane lipids composition change from unsaturated fatty acid to saturated fatty acid.

So the correct answer is option E.
