Succus entericus is
(1) Secretion of goblet cells+ secretion of mucosal brush border cells of intestine
(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?
(1) Dipeptidase
(2) Amylases
(3) Nucleosidases
(4) None of these
Protection of intestinal Mucosa from HCl is carried out by-
(1) Alkaline secretion of pancreas
(2) Sub-mucosal glands of duodenum
(3) Mucus from intestinal goblet cells
(4) All of these
Proteolytic enzyme of pancreas is not
(1) Trypsin
(2) Chymotrypsin
(3) Carboxypeptidase
(4) Protopeptidase
Carbohydrates in the chyme are hydrolysed by pancreatic amylase and results into
(1) Disaccharides
(2) Maltose
(3) Lactose
(4) Sucrose
The succus entericus does not act on
(1) Dipeptides
(2) Nucleotides
(3) Nucleosides
(4) Peptones
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
Nucleosides are acted upon by nucleosidases and give rise to
(1) Sugars and bases
(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..
a. 1. Duodenum and Jejunum; 2.ileum; 3. Large intestine
b. 1. Duodenum; 2. Jejunum and ileum; 3. Large intestine
c. 1. Duodenum and ileum; 2. Caecum; 3. Rectum
d. 1. Duodenum and Jejunum; 2. Ileum; 3. Rectum
Large intestine does not
(1) Secrete mucus
(2) Plays significant role in digestion
(3) Helps in easy passage of waste
(4) Get undigested and unabsorbed substances
