Where is the starch (a type of carbohydrate) in the apple initially broken down?
pancreas
mouth
esophagus
stomach
The monomer of carbohydrates are
nucleotides
fatty acids
amino acids
monosaccharides
The monomer of proteins are
nucleotides
fatty acids

What enzyme is released by the salivary glands?
pepsin
trypsin
sucrase
amylase
What enzyme is released in the stomach?
pepsin
lipase
sucrase
amylase
What does pepsin break down?
carbohydrates
lipids
proteins
nucleic acids
The pancreas and liver release digestive juices into what organ?
stomach
small intestine
large intestine
esophagus
Which accessory organ produces fluid that increases the pH in the small intestine. The fluid stops the work of pepsin in the small intestine.
liver
gallbladder
appendix
pancreas
Where are nutrients absorbed into the blood stream?
stomach
large intestine
small intestine
mouth
The small intestine is covered with fingerlike projections that increase surface area for absorption of nutrients. These projections are called
lacteals
sphincters
mucosa membrane
villi
The small intestine produces many enzymes. Which enzyme in the small intestine breaks down any remaining proteins?
lipase
peptidase
pepsinogen
pepsin
What is the function of bile?
chemical digestion of proteins in the stomach
helps with absorption of water in the large intestine
breaks down lipids into fat droplets
chemical digestion of carbohydrates
If your gallbladder was removed, what foods would you have a hard time digesting?
carbohydrates
nucleic acids
proteins
lipids
What organ is just a passageway in the digestive system?
mouth
small intestine
esophagus
liver
Water is absorbed in which organ?
large intestine
stomach
small intestine
rectum
Enzyme released by salivary glands that breaks down carbohydrates
pancreatic amylase
salivary amylase
lipase
pepsin
The breakdown of food using enzymes
mechanical digestion
persitalsis
segmentation
chemical digestion
Helps break down lipids into fat droplets. Stored in the gallbladder
trypsin
bile
intestinal lipase
salivary amylase
Accessory organ that releases juices into the small intestine. Releases fluid that stops the work of pepsin in the small intestine.
