Digestive Enzymes

Question 1

Enzymes that break down carbohydrates:

Where is Amylase found?

Answer 1

Amylase is secreted by the pancreas into small intestines and salivary glands in the mouth.

Question 2

Enzymes that break down carbohydrates:

What does Amylase do?

Answer 2

Amylase is responsible for the initial process of digestion of carbohydrates.

Question 3

Enzymes that break down carbohydrates:

Where is Maltase found?

Answer 3

Maltase is synthesized by cells of the mucous membrane lining the intestinal wall.

Question 4

Enzymes that break down carbohydrates:

What does Maltase do?

Answer 4

Maltase further breaks down carbohydrates, specifically the sugar, maltose, into glucose.

Question 5

Enzymes that break down carbohydrates:

Where is Lactase found?

Answer 5

Lactase is produced by cells that line the walls of the small intestine.

Question 6

Enzymes that break down carbohydrates:

What does Lactase do?

Answer 6

Lactase functions at the small intestine wall to break down lactose into smaller sugars called glucose and galactose.

Question 7

Enzymes that break down carbohydrates:

Where is Sucrase found?

Answer 7

Sucrase is synthesized by the cells
that line the walls of the intestine.

Question 8

Enzymes that break down carbohydrates:

What does Sucrase do?

Answer 8

The role of the sucrase is to break down sucrose into simple sugars, glucose and fructose.

Question 9

Enzymes that break down proteins:

Where are Proteases found?

Answer 9

Proteases are found mainly in the
stomach and small intestines.

Question 10

Enzymes that break down proteins:

What do Proteases do?

Answer 10

Proteases are enzymes that break down proteins into amino acids.

Question 11

Enzymes that break down proteins:

Where is Trypsin found?

Answer 11

Trypsin is secreted from the walls of
the small intestine.

Question 12

Enzymes that break down proteins:

What does Trypsin do?

Answer 12

Trypsin is used in the secondary step of protein digestion resulting in amino acids.

Question 13

Enzymes that break down proteins:

Where is Pepsin found?

Answer 13

Pepsin is secreted by the stomach as pepsinogen and activated by the gastric acid to pepsin.

Question 14

Enzymes that break down proteins:

What does Pepsin do?

Answer 14

Pepsin is used to digests proteins into smaller units called peptides.

Question 15

Enzymes that break down fats:

Where are Lipases found?

Answer 15

Lipases are found in the small
intestine.

Question 16

Enzymes that break down fats:

What do Lipases do?

Answer 16

Lipases are a group of fat-digesting enzymes found in the blood, gastric juices, pancreatic secretions, intestinal juices, and fat tissues.

Question 17

Enzymes that break down fats:

Where is Lingual Lipase found?

Answer 17

Lingual lipase is an enzyme secreted in the mouth and is swallowed with food and saliva. It accumulates in the stomach between meals.

Question 18

Enzymes that break down fats:

What does Lingual Lipase do?

Answer 18

Lingual lipases are a group of enzymes that breakdown dietary fats.

Question 19

Enzymes that break down fats:

Where is Gastric Lipase found?

Answer 19

Gastric lipases are found in the upper part of the stomach.

Question 20

Enzymes that break down fats:

What does Gastric Lipase do?

Answer 20

Gastric lipases are a group of enzymes which breakdown fats during digestion.

Question 21

Enzymes that break down fats:

Where is Phospholipase found?

Answer 21

Phospholipases are found in the
small intestine.

Question 22

Enzymes that break down fats:

What does Phospholipase do?

Answer 22

Phospholipases are enzymes that break down specific fats called phospholipids during digestion.

Question 23

Enzymes that break down fats:

Where is Cholesterol Esterase found?

Answer 23

Cholesterol Esterase is found primarily in the pancreas but has been detected in other tissues as well.

Question 24

Enzymes that break down fats:

What does Cholesterol Esterase do?

Answer 24

Cholesterol esterase breaks down specific fats into sterols and fatty acids, but required bile salts to complete this action.

Question 25

Enzymes that break down fats:

Where are Nucleases found?

Answer 25

Nucleases are found in the small intestine.

Question 26

Enzymes that break down fats:

What do Nucleases do?

Answer 26

Nucleases are enzymes that degrade nucleic acids, either DNA or RNA. They do this to repair damaged strands of DNA or RNA.

Question 27

Enzymes that break down fats:

Where is Pancreatic Lipase found?

Answer 27

Pancreatic lipase is usually secreted by the pancreas and transferred to the duodenum of the small intestine.

Question 28

Enzymes that break down fats:

What does Pancreatic Lipase do?

Answer 28

Pancreatic lipase breaks down fat, cholesterol esters, and fat-soluble vitamins.
