Adaptations In Gut Flashcards
What enzyme is used to break down cellulose? Where is it produced?
Cellulase breaks down cellulose
Microorganisms host the cellulase
True of false… plants are difficult to digest due to cellulose
True
What kind of teeth do carnivores have? Herbivores?
Carnivores- sharp teeth
Herbivores- molars and pre molars
What internal organ is used to digest cellulose?
Cecum
What is foregut fermentation?
Rumination process is taking place before the area you digest food
What allows for fermentation?
Microbes do not require oxygen
What is mutualistic digestion?
Both parties benefit
What I the process of ruminant digestion?
Rumen
Reticulum
Omasum
Abomasum
What occurs in the rumen?
Microorganisms digest cellulose using cellulase
What occurs in the reticulum?
“Regurgitation” and “chewing the cud”
Microorganisms digest cellulose
(RE)ticulum- (RE)process
What occurs in the omasum?
Re-swallowed cud goes here
Water is absorbed
What occurs in the abomasum? What is the PH of the stomach?
This is the “true stomach”
Digestion occurs of protein. The protein comes from the rumen and the microorganisms found there.
The PH is 2
Where can the microorganisms be found inside an animal?
Rumen
What is a foregut fermenter and what are two examples?
Foregut- fermentation BEFORE small intestines (takes place before absorption)
Cattle, sheep, antelope, goats, camels, moose, deer, giraffes, buffalos
What is a hindgut fermenter and what are two examples of them?
Fermentation occurs after small intestines. This could lead to the loss of many nutrients
Rabbits, horses, zebras, rhinos, apes, elephants, some rodents, several herbivorous ground dwelling birds
