Text Solution

Verified by Experts

1. Growing children require more amount of protein for their growth and development.
2. Protein deficient diet during early stage of children may lead to protein energy malnutrition such as Marasmus and Kwashiorkor.
3. Symptoms are dry skin, pot-belly, oedema in the legs and face, stunted growth, changes in hair colour, weakness and irritability.
4. Marasmus is an acute from of protein malnutrition. This condition is due to a diet with inadequate carbohydrate and protein.
ii. Role of pancreatic enzymes in digestion :
1. Pancreatic juice contains enzymes such as trypsinogen, chymotrypsinogen, carboxypeptidases for protein digestion.
2. Trypsinogen is activated by an enzyme, enterokinase, secreted by the intestinal mucosa into active trypsin.
3. This in turn activates the enzyme chymotrypsinogen in the pancreatic juice.
4. The proteins and partially digested proteins in the chyme from the stomach are acted upon by the proteolytic enzymes of pancreatic juice in the small intestine.
5. Proteins `underset((hydrolysis))overset(Trypsin)to` Pelypeptides + peptones
6. Chymotrypsin hydrolyses peptide bonds associated with specific amino acids .
