hormones and enzymes Flashcards
thyroid hormone
source: thyroid action: stimulates metabolic activity
tyrosine derivative
pancreatic amylase
produced: pancreas function: small intestine action: hydrolyzes starch to maltose
epinephrine and norepinephrine
source: adrenal medulla action: increase blood glucose level and heart rate
also called catecholamines
tyrosine derivative
melatonin
source: pineal gland action: unknown in humans
sucrase
produced: intestinal glands function: small intestine action: hydrolyzes sucrose to glucose and fructose
glucocorticoids
source: adrenal cortex action: increase blood glucose level and decrease protein synthesis
steroid hormone
lactase
produced: intestinal glands function: small intestine action: hydrolyzes lactose to glucose and galactose
thyroid stimulating hormone TSH
source: anterior pituitary action: stimulates the thyroid to produce thyroid hormones
peptide hormone
glucagon
source: pancreas action: stimulates conversion of glycogen to glucose in the liver; increases blood glucose
peptide hormone
maltase
produced: intestinal glands function: small intestine action: hydrolyzes maltose to 2 glucose molecules
somatostatin
source: pancreas action: suppresses secretion of glucagon and insulin
erythropoietin
source: kidney action: stimulates bone marrow to increase production of erythrocytes
prolactin
source: anterior pituitary action: stimulates milk production and
peptide hormone
follicle-stimulating hormone FSH
source: anterior pituitary action: Stimulates follicle maturation in females; spermatogenesis in males
peptide hormone
luteinizing hormone LH
source: anterior pituitary action:stimulates ovulation in females, testosterone synthesis in males
peptide hormone
dipeptidases
produced: intestinal glands function: small intestine action: hydrolyzes pairs of amino acids
calcitonin
source: thyroid action: decreases the blood calcium level
trypsin (secreted as trysinogen)
produced: pancreas function: small intestine action: hydrolyzes speciic peptide bonds, converts chymotrypsinogen to chymotrypsin
chemotrypsin (secreted as chymotrysinoen)
produced: pancreas function: small intestine action: hydrolyzes specific peptide bonds
mineralocorticoids
source: adrenal cortex action: (aldosterone) increases sodium reabsorption and potassium secretion, acts on the kidneys
steroid hormones
oxytocin:
source: produced in hypothalamus; stored in posterior pituitary Action: stimulates uterine contractions during labor and milk secretion during lactation
peptide hormone
pepsin (secreted as pepsinogen)
produced: gastric glands function: stomach action: hydrolyzes specific peptide bonds
growth hormone
source: anterior pituitary action: stimulate bone and muscle growth
peptide hormone
aminopeptidase
produced: intestinal glands function: small intestine action: hydrolyzes terminal peptide bond at amino end
progesterone
source: overy/placenta action: promotes growth/ maintenance of endometrium
steroid hormone
artrial natriuetic hormone
source: heart action: involved in osmoregulation
bile (not an enzyme)
produced: liver function: small intestine action: emulsifies fat
carboxypeptidase
produced: pancreas function: small intestine action: hydrolyzes terminal peptide bond at carboxyl end
insulin
source: pancreas action: lowers blood glucose and increases storage of glycogen
peptide hormone
testosterone
source: testis action: maintains male secondary sexual characteristics
steroid hormone
lipase
produced: pancreas function: small intestine action: hydrolyzes lipids
salivary amylase (ptyalin)
produced: salivary glands site of function: mouth action: hydrolyzes starch to maltose
adrenocorticotropic hormone (ACTH)
source: anterior pituitary action: stimulates the adrenal cortex to synthesize and secrete glucocorticoids (stress hormones)
peptide hormone
thymosin
source: thymus action: stimulates t-lymphocyte development
vasopressin (ADH)
source: produced in hypothalamus; stored in posterior pituitary action: stimulates water reabsorbtion in kidneys
peptide hormone
estrogen
source: ovary/placenta action: maintains female secondary sexual characteristics
steroid hormone
parathyroid hormone
source: parathyroid action: increases blood calcium level
peptide hormone
enterokinase
produced: intestinal glands function: small intestine action: converts trypsinogen to trypsin
