Answer 1

Hint: Digestion is the breakdown of large molecules of food into small water-soluble molecules. Hydrolysis is the breakdown of a substance chemically due to a reaction with water. Enzymes are the protein substances that are produced by living organisms that act as a biological catalyst to bring about a particular biochemical reaction. Glands are the organs that form and release substances that perform a particular function in the body. Exocrine and endocrine are the two types of glands. Endocrine glands release substances from which hormones are made.

Complete answer:
The breakdown products of the blood component hemoglobin are the bile pigments. The two important bile pigments are bilirubin and biliverdin. Bilirubin is orange or yellow whereas biliverdin is green and it is the oxidized form of bilirubin.
Starch is defined as the carbohydrates consisting of a large number of glucose units. Amylases are the enzymes required for the hydrolysis or breakdown of starch into constituent sugars.
Breakdown of fats in food so that they can be easily absorbed in the intestines requires enzyme lipases.
The salivary glands are those glands that produce saliva. Four pairs of salivary glands are Parotid glands, Sublingual glands, Submandibular glands, and Buccal glands.
So, the correct answer is “Option C”.

Additional Information:
Bile pigments are excreted through feces and they give color to the fecal matter.
The salivary glands and pancreas produce amylase.
Lipases are produced in the mouth, pancreas, and stomach.
The salivary glands that produce saliva are exocrine glands.

Note:
Bilirubin and biliverdin are the most important bile pigments. Amylase enzymes are the enzymes that are required for the hydrolysis of starch. It is produced by the salivary gland and pancreas. Digestion of fat occurs by the action of the lipase enzyme. The parotid gland is one of the four pairs of the salivary gland. Glands are the organs that form and release substances that perform a particular function in the body.
