Enterogasterone reduces digestive activity of stomach. Renin is secreted by kidney and regulates blood pressure. Enterokinase activates trypsinogen to trypsin.

Correct Option: D

Enterogasterone reduces digestive activity of stomach. Renin is secreted by kidney and regulates blood pressure. Enterokinase activates trypsinogen to trypsin.

Hypercholesterolemia or high blood cholesterol arises due to excess saturated fat in the diet. In this condition cholesterol deposits on the walls of blood vessels causing reduction in their diameter. This results in rise of blood pressure and other cardiac disorders. The disease can be prevented by taking unsaturated oils in the diet i.e. vegetable oils such as groundnut oils. Butter, ghee, animal fats are all rich in saturated fatty acids.

Protein digestion starts in the stomach with the action of enzyme pepsin. In the duodenum it is performed by the action of trypsin, chymotrypsin & carboxypeptidases (from pancreatic juice). Aminopeptidases & dipeptidases, enterokinase act in jejunum and it ends in the ileum.
