Question 1

Kinase: functions (2)

Answer 1

> is an enzyme that catalyzes (speeds up) the conversion of a proenzyme to an active enzyme

> adds a phosphate molecules to specific substrates (phosphorylation)

Question 2

Carbohydrates: digestive enzymes and location (2)

Answer 2

> mouth: Salivary Amylase

>duodenum: Pancreatic Amylase

Question 3

Proteins: digestive enzymes (3) (3), location (2)

Answer 3

Stomach: Gastrin > HCl > Pepsin

Duodenum: Trypsin, Elastase, Chymotrypsin

Question 4

Lipids: digestive enzymes (4) locations (4)

Answer 4

mouth: Lingual Ligase
stomach: Gastric Lipase
sm Intestines: Pancreatic Lipase
liver: Bile

Question 5

Renin: conversion

Answer 5

Renin converts Angiotensinogen -> Angiotensin I, which converts into Angiotensin II (vasoconstrictor) -> which stimulates secretion of Aldosterone

Question 6

Gastrin: function and target

Answer 6

> stimulates release of HCl

>targets: Stomach

Question 7

Secretin: function and location

Answer 7

> stimulates release of Digestive Enzymes and Bile

>target: Pancreas and Liver

Question 8

Cholecystokinin (CCk): function and target

Answer 8

> stimulates release of Digestive Enzymes and Bile

targets: Pancreas and Liver

Question 9

Parietal Cells: secretes

Answer 9

> binds to B-12 secretes HCl and Intrinsic Factor

Question 10

Pepsin: breaks down

Answer 10

> Proteins

Question 11

Enteroendocrine Cells: secretion chain

Answer 11

Enteroendocrine cells secrete Gastrin –>
Gastrin secretes HCl
thru Parietal Cells

Question 12

Chief Cells: secretion chain

Answer 12

> secretes Pepsinogen, which converts into Pepsin
