Question

The enzyme not secreted by cells present in crypts of Lieberkuhn is
a)Enterokinase
b)Nuclease
c) Nucleotidase
d) Nucleosidase​

Answer 1

Answer:

D option is the correct answer.

Explanation:

Nucleosidase is secreted by intestine

Answer 2

Answer:

Nuclease release by pancreas , not by cells present in crypts of Lieberkuhn.  

Explanation:

• Succus entericus contains different enzymes like disaccharidases , dipeptidases, lipases, nucleosidases. Nuclease is found in the pancreatic juice that is released by pancreas.

• Enteropeptidase is  secreted from intestinal glands (the crypts of Lieberkuhn) following the entry of ingested food passing from the stomach.

• A nucleotidase is secreted by Trichinella spiralis.

• Nucleosidases is responsible to finish the work of the nucleases produced by the pancreas. They break nucleotides into  sugar, phosphate and base.
