Question

Nucleases in the pancreatic juice act on nucleic acids to form

• A. fats
• B. nucleotides
• C. proteins
• D. starch

Answer 1

The correct option is B nucleotides

Nuclease is an enzyme that cleaves phosphodiester bonds between nucleotides in nucleic acids. Nucleases include DNase, which digests DNA, and RNase, which digests RNA. Nucleases in the pancreatic juice act on nucleic acids to form nucleotides.
$\text{Nucleic acids}\stackrel{\text{Nucleases}}{\to }\text{Nucleotides}\stackrel{}{\to }\text{Nucleosides}$

Nucleotides are further digested to nucleosides with the help of nucleotidases, and nucleosides then are digested with the help of nucleosidases.

Proteases break down proteins into amino acids.

Lipases break down triglycerides (fats) into fatty acids and glycerol.

Amylases break down starch into dextrins, maltose, and finally glucose.
