NEET BiologyNCERT Class 11Cell: Structure and Functions
Biomolecules: NEET questions with solutions
This chapter tests the chemistry of amino acids, sugars, lipids and nucleotides, the levels of protein structure, polysaccharides, and enzyme action, inhibition and classification. NEET marks are lost on purine versus pyrimidine, nucleoside versus nucleotide, the order of protein structure levels, and co-factor categories.
