Which of the following is true about membrane proteins embedded within the lipid bilayer?
A) An increased temperature of the bilayer decreases the rate of transverse diffusion of the membrane protein.
B) They undergo transverse diffusion approximately every 5 seconds at body temperature.
C) They undergo transverse diffusion readily at body temperature unless their movement is restricted by other cellular components.
D) As the temperature decreases, lateral diffusion of the membrane protein is restricted in bilayers with lipids which have longer chain fatty acids and fewer double bonds.
E) Lateral diffusion of the membrane protein occurs independent of bilayer composition and temperature.
Answer: D) As the temperature decreases, lateral diffusion of the membrane protein is restricted in bilayers with lipids which have longer chain fatty acids and fewer double bonds.
