Because
lipids are commonly found in fried foods, vegetable oil, butter, whole milk, cheese, cream cheese, and some meats.
and
oligosaccharides are found in plants
In the following questions, a statement of Assertion (A) is given foll...
Explanation:
Assertion (A): Lipids present in the outer and inner side of the bilayer membrane are mostly the same.
Reason (R): Oligosaccharides are attached to the external surface as well as the inner surface of the biomembrane.
- In the structure of the cell membrane, lipids are arranged in a bilayer with hydrophilic heads facing outwards and hydrophobic tails facing inwards.
- The lipids present in the outer and inner sides of the bilayer membrane are mostly the same, consisting of phospholipids, cholesterol, and glycolipids.
- Oligosaccharides are attached to the external surface of the cell membrane, playing a role in cell recognition and communication.
- However, they are not typically attached to the inner surface of the membrane where the hydrophobic tails of the lipids are located.
- Therefore, the Reason provided is not a correct explanation for the Assertion.
- Lipids on the inner and outer sides of the membrane may have different functions despite being similar in composition.
- Hence, option D is the correct answer as both Assertion and Reason are false.
