Why are Cell Membranes refer to as Fluid Mosaic in Structure?
Notes from the video ‘A Level H2 Biology Tuition and H1 Biology Tuition | Cell Membranes are Fluid Mosaic in Structure’:
In this Biology tutorial, we would learn why cell membranes are referred to as fluid mosaic in structure.
Membranes are referred to as ‘fluid’ because the cell membrane is made of phospholipids and proteins which are free to move laterally within a layer while the phospholipids can flip-flop from one layer to another.
Membranes are referred to as ‘mosaic’ because the random arrangement of the proteins embedded amongst the phospholipid molecules resembles a mosaic pattern.
