Unformatted text preview: ) b ) Degree of saturation of phospholipid fatty acid chains: less saturation (more double bonds) = greater fluidity. ( amount of cholesterol in the membrane was also accepted, although this does not answer this question about the structure of membrane lipids) 8. What influence does cholesterol have on the transition temperature of a bio-membrane? (2) Cholesterol acts as a buffer to broaden the transition range so a membrane can remain functional over a broader range of temps. (In general, increased cholesterol decreases membrane permeability and fluidity). Page 1 Name ______________________________ Demo...
