69. The quasi–fluid nature of lipid enables:-Pg-132, easyA) Flip–flop movement of proteins withinthe lipid bilayer.TG: @Chalnaayaaar

An improved model of the structure of cell membrane was proposedby Singer and Nicolson (1972) widely accepted as fluid mosaic model(Figure 8.4). According to this, the quasi-fluid nature of lipid enableslateral movement of proteins within the overall bilayer. This ability to movewithin the membrane is measured as its fluidity.

Which type of movement is LEAST likely for a phospholipid in the cell membrane? [2 marks]A flexion of the carbon chain tailsB flip-flopC lateral diffusionD rotationE bumping into proteins

Which of the following Incorrectly describes the Phospholipid bilayer?Proteins embedded in the bilayer facilitates transport of substances.Phospholipids associates to form two layersThe hydrophobic tails are pointed outward.The hydrophobic tails are pointed inward.
