Phospholipids are important cell membrane constituents because these
1 Contain polar portions only
2 Contain both polar and non-polar portions
3 Contain non-polar portions only
4 Can form bilayer in water
Explanation:
A phospholipid is an amphipathic molecule. The phosphate group is negatively charged making the head polar or “Water loving” and the lipids are uncharged nonpolar and hydrophobic “Water fearing”. This combination is the characteristic of cell membrane.

Statement A : Na+/K+ Pump is an example of Passive transporter. Statement B : Movement of alcohol by diffusion is called osmosis.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
