A. T and U
B. U and V
C. V and W
D. W and T

Answer 1

Answer:

Secretion from pancreas is known as pancreatic juice. Pancreatic juice contains three enzyme. They are trypsin, lipase and amylase. Trypsin helps in the digestion of protein. Lipase helps in converting the emulsified fat into fatty acids and glycerol. Amylase helped in the breakdown of starch into maltose. And also the secretion of gastric glands like hydrochloric acid, pepsin and mucus and produced in stomach. Pepsin helps in the digestion of protein also.

Explanation:

So the answer is pancreas and stomach.

Answer 2

Answer:  D

Explanation: Stomach: The stomach secretes pepsinogen, which is converted to pepsin by stomach acid. Pepsin breaks down proteins into smaller polypeptides.

2. Pancreas: The pancreas secretes several enzymes that break down proteins, including trypsin, chymotrypsin, and carboxypeptidase.

3. Small intestine: The small intestine secretes enzymes called proteases, which break down polypeptides into amino acids. These include enterokinase, aminopeptidase, and dipeptidase.

It's important to note that while these structures secrete enzymes that specifically target protein digestion, many digestive enzymes are multifunctional and can break down other nutrients as well.
