Answer 1

(a) Enzymes are absent in bile

Answer 2

Answer: Enzymes are absent in bile.

Explanation: Bile is a yellowish-brown or olive green liquid with a pH of 7.6-8.6 and consists mostly of water, cholesterol, bile salts, bile pigments, bile acids, lecithin (a phospholipid), and several ions.

• Bile salts consist of sodium and potassium salts of bile acids (mainly chenodeoxycholic acid and cholic acid) that plays an important role in emulsification by breaking down the large lipid globules into a suspension of small lipid globules.

• Cholesterol- Plays an important function in protecting the epithelium of the gall bladder and biliary ducts from the damaging effects of bile salts.
• Bile pigments- Major bile pigment is Bilirubin. They are an important inductive antioxidant system that protects against diverse cellular stresses including oxidative damage.
