Which enzymes are likely to act on the baked potatoes eaten by a man, starting from the mouth and as it moves down the alimentary canal?

Salivary maltase → carboxypeptidase → trypsinogen
Pancreatic amylase → salivary amylase → lipases
Disaccharidase like maltase → lipases → nucleases
Salivary amylase → pancreatic amylase → disaccharidases

Solution

Chemical process of digestion started in the oral cavity by the hydrolytic action of the carbohydrate (potato contains starch) splitting enzyme, the salivary amylase.Carbohydrates in the chyme are hydrolysed by pancreatic amylase into disaccharides.

A healthy person eats the following diet – 5 gm raw sugar, 4 gm albumin, 10 gm pure buffalo ghee adultrated with 2 gm vegetable ghee (hydrogenated vegetable oil) and 5 gm lignin.How many calories he is likely to get?

Solution

Physiological value of carbohydrates is 4.0 kcal/g,proteins 4.0 kcal/g and of fats is 9.0 kcal/g. Hence,
5 g raw sugar will yield
5 × 4.0 = 20.0 kcal
4 g albumin (protein) will yield
4 × 4.0 = 16.0 kcal
10 + 2 g of fat will yield
12 × 9.0 = 108.0 kcal
Total yield = 144 kcal

Cholecystokinin
Pancreozymin
Gastrin
