Choose the incorrect statement about the plasma membrane.
Options
- AThe bilipid layer is made up of phosphoglycerides.
- BThe membrane of the erythrocyte has approximately 40 per cent protein and 52 per cent lipids.
- CPeripheral proteins lie on the surface of membrane while the integral proteins are partially or totally buried
- DThe fluid nature of the membrane is important for functions like cell growth and formation of intercellular ju
Correct answer
B. The membrane of the erythrocyte has approximately 40 per cent protein and 52 per cent lipids.
Step-by-step solution
The lipid component of the membrane mainly consists of phosphoglycerides. The ratio of protein and lipid varies considerably in different cell types. In human beings, the membrane of the erythrocyte has approximately 52 per cent protein and 40 per cent lipids. Peripheral proteins lie on the surface of membrane while the integral proteins are partially or totally buried in the membrane. The fluid mosaic model was introduced by Singer and Nicholson. The fluid nature of the membrane is important for functions like cel
