The correct option is C stomach
The correct option is C:
Explanation of correct option:
1.In the wall of the stomach, millions of gastric glands are present which secrete about 400-800 mL of gastric juice during each meal.
2.The gastric juice contains two enzymes—pepsin and rennin. The enzyme pepsin converts large molecules of protein into smaller molecules called peptones and proteoses. The enzyme rennin changes the milk protein casein into paracasein which is the insoluble curd.
Explanation of incorrect option:
Option A:
Mouth is the beginning of alimentary canal.Saliva is present in the mouth and mixes with food,saliva contains called salivary amylase, which starts digesting the starch and converts it into maltose (sugar).
Option B:
Oesophagus is a long muscular tube approximately 25 cm,which connect pharynx and stomach.Digestion does not takes place in oesophagus.
Option D:
1.The duodenum receives the secretion called bile from the liver.
2.It also receives a secretion called the pancreatic juice from the pancreas which contains some digestive enzymes namely the amylase, trypsin and lipase and helps in digestion of carbohydrates,proteins and fats.
Final answer:Pepsin, a protein digesting enzyme is present in the stomach.
