Animal Nutrition Clues:
Across
1
the inactive form of a protease enzyme manufactured by chief cells in the stomach
5
the organ which produces most digestive enzymes as well as both insulin and
glucagon
8
the portion of the alimentary canal connecting the pharynx with the stomach
10
an organism with an exceptionally long digestive system, a cecum, and many
grinding teeth (molars)
15
the type of amino acid that, by its presence, defines a protein as complete or
incomplete
19
a condition in which an organism obtains enough calories but not enough essential
nutrients to be healthy
20
a nutrient that an organism cannot make from raw materials; these must be
ingested
23
the organ that releases glucose as a response to glucagon
24
the final step in food processing in mammals
25
the storage organ for bile
26
the third step in the processing of food in mammals
Down
1
the cavity immediately anterior to the
2
a flap which covers the entrance to the trachea and directs food down the
esophagus
3
the location in the alimentary canal where most of the reabsorption of water
occurs
4
a portion of the digestive system
6
a complete digestive tube in some animals that begins at the mouth and ends at
the anus (2 words)
7
an epidemic problem in America defined as the intake of too many calories
8
digestion that occurs outside of the cell such as by fungal hyphae
9
the enzyme released in the oral cavity which begins the chemical digestion of
carbohydrates
11
a ball of lubricated chewed food at the anterior end of the digestive system
12
the first portion of the small intestine in which most of the absorption of food
monomers occur
13
an animal which eats other animals
14
the rhythmic contractions that propel a bolus of food through the alimentary
canal.
16
a muscular ring that regulates the movement of a bolus of food
17
an inorganic substance that often acts as a cofactor in enzymes
18
an organic molecule that typically acts as a coenzyme in reactions
21
a single structure that increases the absorptive surface area in the small intestine
22
a chemical in the digestive system which emulsifies fat when added to the small
intestine
