BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Nucleic acids (DNA and RNA) in foods are digested in the small intestine with the help of both pancreatic enzymes and enzymes produced by the small intestine itself. Pancreatic enzymes called ribonuclease and deoxyribonuclease break down RNA and DNA, respectively, into smaller nucleic acids.

Detailed explanation-2: -The nucleic acid adenosine triphosphate (ATP), made up of an adenine nitrogenous base, a 5-carbon ribose sugar, and three phosphate groups, is involved in generating energy for cellular processes.

Detailed explanation-3: -Unlike the other three macromolecules (carbohydrates, lipids, and proteins), nucleic acids are not used for energy production; therefore, the results stated in this question don’t seem valid. Both DNA and RNA are made up of nucleic acids.

Detailed explanation-4: -Nucleases are enzymes which break down nucleic acids to free nucleotides. These enzymes are present in the pancreatic juice.
