The Lipid Bilayer Forming Cell Membranes Behaves As A 2d Fluid Whose Fluidity Depends Largely On Its Lipid Composition 2 (11.38 KiB) Viewed 200 times
The lipid bilayer forming cell membranes behaves as a 2D fluid whose fluidity depends largely on its lipid composition. Phospholipid molecules in the bilayer can diffuse laterally, and the rate of diffusion as a proxy for fluidity can be observed using FRAP experiments. Which of the following changes would lead to longer recovery time from photobleaching? a. Adding more cholesterol to the membrane composition O b. Decreasing cis-double bond content relative to trans-double bond content in the phospholipids c. Increasing unsaturated phospholipid content d. Removing membrane-embedded proteins
Phospholipid bilayers are virtually impermeable to which of the following? a. H2O (water) O b. Mg2+ O c. 02 (oxygen) O d. steroid hormones
