monogastric digestion Flashcards
Enzyme action in the mouth-
⎁amylases hydrolyses the ⎁(1-4) glucan links in polysaachrides containing three or more ⎁(1-4) D glucose units
what is salvia made up of?
99% water
1% mucun, inorganic salts, enzymes, alpha amylases lysozyme
what animals dont have salivary alpha amylase
horses and dogs
pigs salvia is what ph
7.3
the main metabolic activity In the body
the liver
what is the function of the stomach
1.ph less than 4
2.secret HCL
3.SECRETE pepsinogen >protein digestion
4.regulate movement of digests into small intestine
5.barrier to harmful microorganisms
capacity of an adult pig stomach
8L
Cardic region
produce mucus (provide protection)
fundic region
secrets HCL, Mucus, enzymes
Pyloric region
secretes mucus
Duodenum
site of mixing digests and secretions
jejunum
main site absorption (villi)
where is bile stored
gall bladder
how is bile secreted from the liver into the duodenum
through bile duct which contain sodium and potassium salts of bile
main digestive gland in the body
pancreas
trypsin
protease that cleaves proteins at the basic AA
chymotrypsin
protease that cleaves proteins at the aromatic AA
Carboxypeptidase
protease that takes off the terminal acid group from a protein
Pancreatic amylase
degrades carbohydrates
Small intestine enzymes
sucrase—>sucrose–>glucose &fructose
Maltase—>maltose—>glucose
iso maltase—->maltose
lactase—->lactose—->glucose and galactose
intestinal lipase—->fatty acids
facilitative
carrier transports the molecule down its concentration gradient
active transport
carrier has two specific binding sites and the organic nutrients is attached to one while the other contains a sodium ion
large intestine
caecum, colon, rectum
what can bacteria also synthesise in LI
Vit B
Crop
out pocketing of the oesophagus that storage for consumed food
proventriculus
glandular stomach where the first significant amount of juices are added
gizzard
a muscular organ used to drink and break up food
Cloaca
common chamber into which the digestive urinary and reproductive tracts open
SI and LI two large sacs what is it called?
caeca
stomach is X% of total tract in hind gut
10%
large intestine of hind gut fermenter is
analogous to rumen
