Question

Consider this flow chart and a list of properties given after that.

1. Molecular weight ranging from 18-800 daltons approx.
2. Proteins, nucleic acids, polysaccharides, and lipids.
3. Chemicals more than 800 daltons molecular weight.
4. Has monomers.
5. It generally has polymers.
Which of these are applicable to (A) and (B) ?

• A. (A): 1, 2, 3 and (B): 4, 5
• B. (A) : 2, 4 and (B) : 1, 3, 5
• C. (A) : 1, 4 and (B) : 2, 3, 5
• D. (A) : 1, 3, 5 and (B) : 2, 4

Answer 1

Answer: (C)

The given procedure is about chemical analysis of the living matter. The filtrate is the acid-soluble pool while the retentate is the acid-insoluble pool. The acid-soluble pool has biomicromolecules containing low molecular weight molecules having a molecular weight between 18-800 daltons. They are generally monomers such as amino acids, monosaccharides, etc. The acid-insoluble pool has biomacromolecules containing high molecular weight molecules having a molecular weight above 800 daltons. They are generally polymers such as carbohydrates, proteins, nucleic acids, etc.
