Which enzymes are secreted only by the pancreas?nucleases
amylase and proteases
lipases
amylase, proteases, lipases, nucleases

Answers

Answer 1
Answer:

Nucleases are the enzymes that are unique to the pancreas. These are enzymes which break down nucleic acids DNA and RNA into nucleotides. When these nucleotides reach the ileum, they are further degraded or digested into sugars, bases and phosphates. These nucleases are known as DNAase and RNAase

Other pancreatic enzymes such as amylase and protease are also produced by other digestive organs such as the salivary glands and the small intestine respectively. However no other digestive organ has been known to produce nucleases apart from the pancreas.

Nucleases are of two  main types, namely exonucleases which cut off the end of a nucleotide and endonucleases which will cut out certain nucleotide sequences right in the middle of a nucleic acid.
Answer 2
Answer:

The enzymes that are secreted only by the pancreas are amylase, proteases, lipases, and nucleases. Therefore, option (4) is correct.

Digestive organs include the pancreas. It secretes digestive enzymes into the small intestine to facilitate food digestion. Amylase breaks starches into sugar molecules. Trypsin and chymotrypsin break proteins into amino acids. Fatty acids and glycerol from lipases aid fat breakdown and absorption.

Finally, nucleases break down DNA and RNA into nucleotides. The pancreas exclusively produces and secretes these enzymes to aid small intestine digestion and absorption. Therefore, option (4) amylase, proteases, lipases, and nucleases is correct.

Answers

(C) because when substances dissolve in it completely, it is called solution which has a even colour all over and no things settled down. But when we see undissolved things that do not settle down, it is called an colloid which make the visibility through it a little opaque and not clear like in the solution
