Which of the following is not true?

Question

BlackTom AI · Accepted Answer

Let’s examine each statement carefully to determine which one is not true.

Option a: 'Bile has an important role in fat digestion.' This is true. Bile aids fat emulsification, increasing the surface area for lipase to act, which is essential for fat digestion.

Option b: 'Bile is a salt solution which contains bile salts, cholesterol, lecithin, bile and pigments.' This is broadly accurate. Bile is a watery, alkaline secretion rich in bile salts, cholesterol, lecithin (a phospholipid), bile pigments (such as bilirubin), and other components that help digest fats.

Option c: 'Bile is made by the gallbladder, and stored in the liver.' This is the statement that is not true. Bile is produced by the liver and then stored in the gallbladder; it is not made by the gallbladder, nor stored in the liver.

Option d: 'Lipase is involved in fat digestion.' This is true. Lipase is the enzyme that hydrolyzes triglycerides into fatty acids and monoglycerides, playing a key role in fat digestion.

In summary, all statements are true except option c, which contains the incorrect claim about the organs that produce and store bile.
