Quiz Answer Key and Fun Facts

1. Which of the following is not one of the salivary glands?

Answer: Adenoids

The parotid, sublingual and submandibular glands secrete saliva into the mouth. They are exocrine glands located in the front of the ears, beneath the tongue and under the lower jaw. The adenoids consist of lymphatic tissue, located at the back of the nose.

2. Saliva is one of the strongest acidic fluids of the body, containing enzymes that aid in the digestion of some foods.

Answer: False

Saliva does contain important digestive enzymes but it is only mildly acidic- pH 6.5-7.0.

3. To differentiate human enzymes from hormones which of the following is primarily true?

Answer: Hormones are produced in ductless glands and secreted into the blood stream

Enzymes are secreted directly into the intestinal tract, including the mouth, stomach and small intestines and assist in the breakdown of ingested foods.

4. Which of these does not produce digestive enzymes?

Answer: Thyroid

The stomach is not truly an exocrine gland but specific cells in the stomach lining secrete pepsin which breaks down proteins into peptones.

5. The enzyme called lipase is a catalyst for the metabolism of which of these foods?

Answer: Fats

Lipase is primarily produced by the pancrease and is released directly into the ileum through the pancreatic duct. Some lipase is also produced by the liver.

6. The enzyme called peptidase is a catalyst for the metabolism of which of these foods?

Answer: Red meats

Proteolytic enzymes, such as peptidase, are secreted by both the salivary glands and the pancreas. Peptidase is the currently approved name for the enzyme previously designated under the general of term of protease.

7. The enzyme named ptyalin is a catalyst for the metabolism of which of these food?

Answer: Starches

Ptyalin is an alpha-amylase secreted by the salivary glands. On swallowing with foods it can continue to digest up to 40 percent of the starch in the stomach.

8. Which artificially produced digestive enzyme is used in the treatment of patients with cystic fibrosis?

Answer: Pancreatic peptidase

Patients with cystic fibrosis develop a clogging of the pancreatic duct and thus have inadequate pancreatic enzymes for digestion, especially for proteins. Oral pancreatic enzyme products are available for these patients.

9. Which artifically produced enzyme-inhibitor is used for the treatment of patients who are HIV positive (the virus that causes AIDS)?

Answer: Protease-inhibitors

For many patients who are HIV positive the oral administration of a protease-inhibitor will reduce the virus count within the cells. It is not used alone and is not a cure.

10. Which of these is not an enzyme, natural or artificial, that is used for medicinal or research purposes?

Answer: Stomach gastrin

Ribonuclease is used to break down DNA in the laboratory. Urease is specific for the break down of urea and is not used normally by humans. L-asparaginase is being used experimentally for treating leukemia and it may prevent tooth decay.
