Question

1)Suppose you were culturing a population of bacteria at 37 degrees C and then reduce the temperature of the culture to 15 degree C. Immediately upon the decrease in temperature what would happen to the membrane fluidity of the cells?

The fluidity of the membrane decreases due to principles of thermodynamics.
The fluidity of the membrane increases due to principles of thermodynamics.
The fluidity of the membrane would be unchanged since membrane fluidity for each species is constant.

2) What property of a molecule will determine whether it facilitated across the membrane or simply diffuses across the membrane?
