Transcribed Image Text:When the movement of lipids in biological membranes was measured, it was
observed that:
OA) Saturated lipids move slower
B) Transverse (across the bilayer) movement is slower than lateral movement
C) Transverse (across the bilayer) movement is faster than lateral movement
D) Proteins move faster than lipids
Expert Solution
Step 1
The cell membrane is a phospholipid bilayer.
According to the Fluid Mosaic Model, the cell membrane is a mosaic of lipids in which the membrane proteins are interspersed.
The maintainance of appropriate fluidity of the membrane is necessary for cell viability.
