NEETBotanyBiomolecules (B)
Arrange the following cellular components in ascending order of their percentage of total cellular mass. (a) Proteins (b) Lipids (c) Carbohydrates (d) Nucleic acids Choose the correct answer from the options given below:
Options
- A(a), (d), (c), (b)
- B(b), (d), (c), (a)
- C(c), (b), (d), (a)
- D(b), (c), (d), (a)
Correct answer
D. (b), (c), (d), (a)
Step-by-step solution
According to the NCERT data for the average composition of cells, the percentage of total cellular mass for various biomacromolecules is as follows: Water: 70-90 % Proteins: 10-15 % Nucleic acids: 5-7 % Carbohydrates: 3 % Lipids: 2 % Ions: 1 % Arranging the given components in ascending order of their percentage mass, we get: Lipids ( 2 % ) This corresponds to the sequence (b), (c), (d), (a). Answer: (b), (c), (d), (a)
