Biology - Digestion and Absorption Question with Solution | TestHub
The end products of protein digestion is (a) and nucleic acid digestion is (b).
Options:
Answer:
Solution:
Proteins are polymers of amino acids. During digestion, proteolytic enzymes like pepsin, trypsin, chymotrypsin, and various peptidases break down proteins into their constituent amino acids.
Nucleic acids (DNA and RNA) are polymers of nucleotides. Pancreatic nucleases first break them down into nucleotides. Intestinal nucleotidases then convert nucleotides into nucleosides by removing the phosphate group. Finally, nucleosidases break down nucleosides into pentose sugars and nitrogenous bases.
Thus, the end product of protein digestion is amino acids, and the end products of nucleic acid digestion are sugars and nitrogenous bases.
Answer: (a) Amino acid, (b) sugar + nitrogenous base
