Accessory organs, enzymes, & Hormones

Question 1

Chemical Digestion

Answer 1

The use of enzymes to breakdown food macromoles/ The use of hormones-messenger molecules to trigger the release of enzymes

Question 2

Amylase

Answer 2

Carbohydrate-digesting enzyme found within the mouth, breaks down starch into disaccharides (smaller chains). Found in saliva and released by the salivary glands

Question 3

Pepsin

Answer 3

Pepsinogen is released into the stomach cavity where it reacts with HCl and converted into pepsin. It digests proteins into stomach

Question 4

Gastin

Answer 4

Release of HCl and pepsinogen in stomach

Question 5

Ulcers

Answer 5

Mucus protects the lining of the stomach from the pepsin and HCl. when mucus layer breaks down, lining is exposed

Question 6

Secretin

Answer 6

Activated and released from the epithelial cells that line small intestine, stimulates liver to secrete bile, encourages pancreas to neutralize acidic chyme

Question 7

Liver

Answer 7

Detoxifies harmful substances in blood, breaks down old red blood cells, stores vitamins and glycogen, produces bile (speeds up digestion of lipids/fats) Activate lipases (chemical digestion of lipids)

Question 8

Gallbladder

Answer 8

Stores bladder until needed, bile released by hormone CCK

Question 9

CCK

Answer 9

fat-rich chyme in small intestine, travels through bloodstream and causes pancreas to release digestive enzymes and gallbladder to release bile

Question 10

Pancreas

Answer 10

Contains enzymes that breakdown proteins (trypsin), carbohydrates (pancreatic amylase), & fats (lipids) and protects lining of the small intestine from gastric juices (stimulated by secretin)

Question 11

Bile

Answer 11

made in liver, stored in gallbladder, emulsifies fat
