Select the correct statement from the following regarding cell membrane.
A
and 
ions move across cell membrane by passive transport. B
Proteins make up 
of the erythrocyte cell membrane.
of the erythrocyte cell membrane. C
Lipids are arranged in a bilayer with polar heads towards the inner part.
D
Fluid mosaic model of cell membrane was proposed by Singer and Nicolson.
Text Solution
Verified by ExpertsThe correct answer is:
D
In human beings, the plasma membrane of erythrocyte has approximately 
protein and 
lipids. Lipids form a bilayer with hydrophilic heads pointing outwards. Cell membrane allows transport of some molecules by passive transport e.g., water, neutral solutes while some are transported actively e.g., 
pump.
