(b) What is emulsification of fats ?

(c) Which protein digesting enzyme is present in pancreatic juice ?​

Answer 1

$\boxed{\huge{ \bf \red{Answer}}}$

▶️(a)(i) It sterilises food by killing pathogens and other microbes.

(ii) It has a pH of 2, which is perfect for entyaus such as pepsin to break down proteins as effectively as possible.

(iii) Helps emulsify food (digestion of protein and stimulates the pancreas to produce digestive enzymes and bile) and protects against harmful ‘ bacteria'.

▶️(b) Breakdown of large gloubule fats into smaller fats droplets is known as emulsification.

▶️(c) Trypsin is the enzyme secreted by the pancreas which aids in digestion of proteins.

Answer 2

Hello!

(a) Role of HCl in stomach

•HCl is a strong acid..which is released by the Gastric Glands

• HCl helps in the digestion of proteins

• HCl converts the inactive pepsinogen into pepsin and helps in protein digestion

(b) Emulsification of Fats

• Fats are the primary metabolites

• Conversion of Fat globules into Fatty acids or glycerol is called as Emulsification of Fats

(C) Protein digestion enzyme in Pancreatic juice

• The enzyme Trypsin - helps in digestion of proteins
