C
Supplied with capillaries and the lacteal vessels

Fatty acids and glycerol
Question 7
Which one of the following is the correct matching of the site of action on the given substrate, the enzyme acting upon it and the end product?
(1) Stomach: Fats  —Lipase—► micelles
(2) Duodenum: Triglycerides —Trypsin—► monoglycerides
(3) Small intestine: Starch —(α)Amylase—► Disaccharide (Maltose)

Question 8
If for some reason our goblet cells are non-functional this will adversely affect

Secretion of sebum from the sebaceous glands
D
Maturation of sperms
Question 9
What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor?
