levels of circulating hormone Flashcards
what does a hormone’s blood concentration depend on
how fast it is synthesized and eliminated
what is positively correlated in the levels of circulating hormones
hormone release and its concentration in blood
what occurs in multiple ways in levels of circulating hormones
hormone elimination
what does it mean that hormone release and its concentration in blood are positively correlated
the more the hormone is released the higher concentration found in the blood
what does it mean that hormone elimination occurs in multiple ways
1 way for example—– cells in the liver degrade the hormones; they have enzymatic degradation
2nd way) removal of hormone in the blood via kidneys
3rd way) target cell uptake of hormone betting to target cell- —-being used - then not be in the blood as much
if you have a faster elimination rate of hormone what happens to the concentration of hormone
concentration of hormone is lower
what is half-life
time necessary to reduce a hormone’s concentration to half of its original level
what is half- life depended on
depends on how efficiently it is eliminated
how should hormones with short half-life be secreted
frequently
why should hormones with short half-life be secreted frequently
to maintain normal concentration
what type of half-life do water soluble hormones generally have
short half-life
what type of half-life do steroids generally have
long half-life
why do steroids generally have a long half-life
steroids have carrier protein that protects them
what is the half-life for testosterone (steroid)
12 days
what is the half-life for the small peptide hormones
a few minutes
