Statement –I : The acid soluble pool contains all lipids, amino acids and sugar.
Statement-II : Nucleotides are biomicromolecules 

Statement I is incorrect. The acid-soluble pool typically refers to the pool of metabolites or small molecules that are soluble in acid and can be extracted from cells or tissues using acidic conditions. However, it does not typically include lipids. Lipids are not soluble in acid but rather are soluble in non-polar solvents such as chloroform or ether. The acid-soluble pool might contain amino acids, sugars, nucleotides, organic acids, and other small molecules that are soluble in acidic conditions.

Statement II is correct. Nucleotides are indeed biomolecules. They are the building blocks of nucleic acids like DNA and RNA. A nucleotide is composed of a nitrogenous base (adenine, thymine, cytosine, guanine, or uracil in RNA), a five-carbon sugar (ribose in RNA or deoxyribose in DNA), and one or more phosphate groups.
