Which among the following is incorrect about the structure of plasma m...
Integral Proteins on Plasma Membrane
The statement that the proteins present on the surface of the plasma membrane are called integral proteins is incorrect. Integral proteins are actually embedded within the lipid bilayer of the plasma membrane. These proteins have regions that are hydrophobic and interact with the hydrophobic tails of the lipid molecules, allowing them to be firmly anchored in the membrane.
Structure of Plasma Membrane
- The plasma membrane is indeed composed of lipids and proteins. The lipid component primarily consists of phospholipids, which have a hydrophilic head and hydrophobic tail.
- The proteins in the plasma membrane can be integral proteins, as mentioned earlier, or peripheral proteins that are attached to the surface of the membrane.
- The plasma membrane forms a lipid bilayer structure, with the hydrophobic tails of the phospholipids facing inward and the hydrophilic heads facing outward towards the aqueous environments inside and outside the cell.
Amphipathic Lipids
- Lipids with both hydrophobic and hydrophilic properties are called amphipathic lipids. Phospholipids are a common example of amphipathic lipids, with their hydrophobic tails and hydrophilic heads.
- The amphipathic nature of these lipids is crucial for the formation of the lipid bilayer in the plasma membrane, as it allows them to self-assemble and create a barrier between the internal and external environments of the cell.
In summary, while the plasma membrane is indeed a lipid bilayer composed of lipids and proteins, the proteins embedded within the membrane are termed integral proteins, not those present on the surface. Additionally, the presence of amphipathic lipids contributes to the structural integrity and function of the plasma membrane.

Plasma membrane is made of lipids and proteins. Lipids with hydrophobic and hydrophilic end are called amphipathic lipids. The plasma membrane is a lipid bilayer membrane. Integral proteins are not just present on the surface of the membrane but span along the entire width of the membrane.
