Question

Which of the following statements about digestive processes is true?

• A. (A) Amylase, maltase, and lactase in the mouth digest carbohydrates.
• B. (B) Trypsin and lipase in the stomach digest protein.
• C. (C) Bile emulsifies lipids in the small intestine.
• D. (D) No food is absorbed until the small intestine.

Answer 1

Answer: (C)

(C) Bile emulsifies lipids in the small intestine.

Answer 2

Explanation:
'Bile emulsifies lipids in the small intestine.' is true about digestive processes. Lipid digestion begins in the stomach with the aid of lingual lipase and gastric lipase. However, the bulk of lipid digestion occurs in the small intestine due to pancreatic lipase. When chyme enters the duodenum, the hormonal responses trigger the release of bile, which is produced in the liver and stored in the gallbladder. Bile aids in the digestion of lipids, primarily triglycerides by emulsification. Emulsification is a process in which large lipid globules are broken down into several small lipid globules. These small globules are more widely distributed in the chyme rather than forming large aggregates.Hence, the correct option is (C).
