Answer 1

$\huge{\underline {\underline {\sf {❥ \: Answer }}}}$

Fluid Mosaic Model was developed to describe the cell membrane.

Answer 2

FLUID MOSAIC MODEL by scientists was developed to explain the cell membrane structure. (OPTION C)

FLUID MOSAIC MODEL -

• The structure was proposed by Singer and Nicolson explaining the structure of the cell membrane.
• It explains plasma membranes as the mosaic of the components such as cholesterol, proteins, phospholipids, and carbohydrates.
• The lipid bilayer separates the protoplasm from the extracellular fluid.
• Proteins are the integral part present in the membrane that allows the transport of substances in and out of the cell.
• Carbohydrate forms the third mosaic layer and binds with proteins and lipids to form glycoprotein and glycolipid respectively.
• The fluidity of the membrane is maintained by the concentration of fatty acids and cholesterol acts as a buffer system.
