Cellulose<\/p>\n\n\n\n<p><strong>Answer:<\/strong> B<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>Maltose is a reducing sugar because it has a free aldehyde group. Sucrose is non-reducing as both anomeric carbons are involved in glycosidic bonding. This is one of the most frequently asked <strong>Top 5 Biomolecules Questions<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Question 2: Amino Acids Structure<\/h3>\n\n\n\n<p>Which functional groups are present in amino acids?<\/p>\n\n\n\n<p>A. \u2013OH and \u2013CHO<br>B. \u2013COOH and \u2013NH\u2082<br>C. \u2013COOH and \u2013OH<br>D. \u2013NH\u2082 and \u2013CHO<\/p>\n\n\n\n<p><strong>Answer:<\/strong> B<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>All amino acids contain both a carboxyl group (\u2013COOH) and an amino group (\u2013NH\u2082). This is a basic NCERT concept commonly tested in <strong>Top 5 Biomolecules Questions<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Question 3: Enzyme Activity<\/h3>\n\n\n\n<p>Which factor does NOT affect enzyme activity?<\/p>\n\n\n\n<p>A. Temperature<br>B. pH<br>C. Substrate concentration<br>D. Light<\/p>\n\n\n\n<p><strong>Answer:<\/strong> D<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>Enzyme activity depends on temperature, pH, and substrate concentration. Light generally does not affect enzyme activity. This is a conceptual question often included in <strong>Top 5 Biomolecules Questions<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Question 4: Protein Structure<\/h3>\n\n\n\n<p>Which structure of protein is determined by hydrogen bonding?<\/p>\n\n\n\n<p>A. Primary<br>B. Secondary<br>C. Tertiary<br>D. Quaternary<\/p>\n\n\n\n<p><strong>Answer:<\/strong> B<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>Secondary structure (\u03b1-helix and \u03b2-pleated sheet) is stabilized by hydrogen bonding. This is a frequently repeated concept in <strong>Top 5 Biomolecules Questions<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Question 5: Vitamins<\/h3>\n\n\n\n<p>Which vitamin is water-soluble?<\/p>\n\n\n\n<p>A.
