Q. No.Gastric lipase do not work because
(1) Lipases are very less in amount
(2) No bile is there to activate lipase
(3) Fats are inaccessible in stomach because of rugae
(4) Lipases act in the presence of trypsin, a pancreatic enzyme.

Succus entericus is

(2) Secretion of intestinal goblet cells
(3) Secretion of brush border intestinal cells
(4) Secretion of pancreatic exocrine portion
Which of the following is not an enzyme of intestine?

Final steps of digestion occur -
(1) Occurs very close to mucosal epithelium of intestine
(2) Occurs in lumen of intestine
(3) Occurs inside mucosal epithelia of intestine
(4) Occurs in the rugae if intestine

(2) Sugars, bases and phosphates
(3) Sugars and phosphates
(4) Bases and phosphates
Final digestion occurs in….1..and absorption occurs in …2… while undigested passes to ..3..
