This experiment (shown in figure ) was performed at 37degree C. If the experiment were carried out at 10 degree C, what effect would you expect on the rate of diffusion? Why?


#Unit 2. Cellular Organization

  1. Increase. Movement of individual lipids in bilayers occurs much faster at 37 degree C, when the lipids are in the “fluid” phase, than at 10 degree C, when they are in the “solid” phase.

  2. Decrease. Movement of individual lipids in bilayers occurs much slower at 37 degree C, when the lipids are in the “fluid” phase, than at 10 degree C, when they are in the “solid” phase.

  3. Increase. Movement of individual lipids in bilayers occurs much slower at 37 degree C, when the lipids are in the “fluid” phase, than at 10 degree C, when they are in the “solid” phase.

  4. Decrease. Movement of individual lipids in bilayers occurs much faster at 37 degree C, when the lipids are in the “fluid” phase, than at 10 degree C, when they are in the “solid” phase.
