Question

You are examining a newly discovered organism that you found living in an extremely hot environment. You notice that its cellular membrane has a relatively low level of cholesterol molecules dispersed though out the phospholipids (around 20%). Question: If you were to place this organism in an extremely cold environment, what would you expect to see change in regard to cell membrane permeability to glycerol? 1 5 3 No cholesterol 20% of lipids cholesterol 50% of lipids cholesterol 10 20 Temperature (C) A. The membrane would become more permeable to glycerol B. The membrane would become less permeable to glycerol. C. The membrane's permeability to glycerol would not change.

Explanation / Answer

As we can see in the graph that is we decrease the temperature the permeability of glycerol decreases.

So in very cold temperature the permeability is likely to be decreased. So,

B. The membrane will become less permeable
