The Cell Membranes of Antarctic Ice Fish Might Have Which

Question

The cell membranes of Antarctic ice fish might have which of the following adaptations?
A) very long chain fatty acids
B) branched isoprenoid lipids
C) a high percentage of polyunsaturated fatty acids
D) a higher percentage of trans-fatty acids
E) no cholesterol

Accepted Answer

Antarctic ice fish live in extremely cold temperatures and require a more fluid cell membrane to keep their membrane functions working properly. A higher percentage of polyunsaturated fatty acids allows the membrane to be more fluid in these conditions.
