हिन्दीConsider the following statements regarding biomolecules and analytical fractions: (A) The acid-soluble pool represents roughly the cytoplasmic composition with compounds having molecular weights ranging from 18 to around 800 daltons. (B) The acid-insoluble fraction contains proteins, nucleic acids, polysaccharides, and lipids. (C) Lipids are strictly macromolecules having molecular weights exceeding 10,000 daltons. (D) Lipids appear in the acid-insoluble fraction because cell membranes break into water-insoluble vesicles during tissue grinding. Which of the above statements are correct?
Correct answer · Option 2
(A), (B) and (D) only
Explanation
Statement (C) is incorrect because lipids have molecular weights not exceeding 800 daltons and are not strictly macromolecules. Statements (A), (B), and (D) are correct.
