Answer 1

Digestive enzymes are compounds that are secreted to aid the absorption of food by the salivary glands and cells lining the liver, pancreas and small intestine.

Complete answer:
Salivary juice produces amylase, a starch separating enzyme. The amylase in saliva is known as ptyalin. Pepsin is the main protein-digesting (proteolytic) enzyme in the stomach. Pepsin is secreted as a proenzyme of pepsinogen, which is activated in pepsin when exposed to acid in the stomach. A component of pancreatic juice is trypsin, where trypsinogen is involved. Trypsinogen is activated by trypsin when added to enterokinase. In the intestinal juice, there are a number of disaccharidases, such as maltase, lactase, sucrase, which split disaccharides into monosaccharides that are readily consumable.

In the mouths of certain creatures, including humans, saliva is the watery and typically rather frothy material formed. Saliva is 98 percent water produced in the salivary glands, but it contains many essential substances, including electrolytes, mucus, antibacterial compounds and different enzymes.
The complex mixture of water, hydrochloric acid, electrolytes (sodium, potassium, calcium, phosphate, sulphate and bicarbonate) and organic compounds is gastric juice (mucus, pepsins, and protein).
Pancreatic juice is a pancreatic fluid that includes a number of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, nucleases, amylase, and pancreatic lipase.
The intestinal glands lining the small intestine secrete digestive juice. The enzyme that transforms trypsinogen to active trypsin, aminopeptidase, nucleases, and nucleotidases requires a number of enzymes, including enteropeptidase.

Hence, the correct answer is option (A)

Note: By separating the large complex molecules that makeup proteins, carbohydrates and fats (macronutrients) into smaller ones, digestive enzymes aid in digestion, allowing the nutrients from these foods to be quickly ingested into the bloodstream and transported around the body.
