Pancreas

Question 1

Isle of Langerhorns

Answer 1

apart of endocrine pancreas

Question 2

Acinar Cells

Answer 2

part of exocrine pancreas, produces digestive proenzymes and bicarbonate buffer

Question 3

Bicarbonate Buffer

Answer 3

protects small intestine lining from acidic chyme, decreases pH of intestines

Question 4

Lipase

Answer 4

digests lipids, activated by bile salts

Question 5

Amylase

Answer 5

digests starch into disaccharides, secreted in active form

Question 6

Protease

Answer 6

digests proteins to amino acids and small peptides

Question 7

Insulin

Answer 7

51 amino acid peptide hormone, made by beta cells of pancreas, parasympathetic division (vagus nerve and Ach), glucose and amino acids from feed stimulate release

Question 8

Glucagon

Answer 8

29 amino acid polypeptide hormone, alpha cells make it, neural and humoral factors (hormone), amino acids stimulate release

Question 9

Exocrine Pancreas

Answer 9

makes digestive proenzymes, bicarbonate buffer, travel from pancreatic duct to duodenum of small intestine. Pancreatic proenzymes help digest food

Question 10

Endocrine Pancreas

Answer 10

hormones, transported to target tissues by blood, mainly insulin and glucagon (aid in regulation of blood glucose)

Question 11

Proteolytic Enzymes

Answer 11

Trypsinogen
Chymotrypsinogen
Proelastase
Procarboxypeptidate A and B

Question 12

Tyrosine Kinase Insulin Receptor

Answer 12

transmembrane, insulin binding location on target tissue to initiate response

Question 13

G-Coupled Protein Receptor

Answer 13

where glucagon binds on liver cells, initiates cellular signaling cascade, triggers metabolism of carbs, fats, proteins inside cell

Question 14

Trypsinogen

Answer 14

activated to trypsin

Question 15

Chymotrypsinogen

Answer 15

activated to chymotrypsin

Question 16

Proelastase

Answer 16

activated to elastase

Question 17

Procarboxypeptidase A and B

Answer 17

activated to Carboxypeptidase A and B
