What is it called when low hormonal levels in the bloodstream cause target cells to increase their number of receptors? Down-regulation Hormone amplification Up-regulation Antagonistic effect What is it called when multiple hormones act together to produce a desired product? Permissive effect Hormone amplification Synergistic effect Antagonistic effect What is it called when the first hormone enhances a target cell’s response to a second hormone? Permissive effect Hormone amplification Synergistic effect Antagonistic effect True or False: For each statement, circle True or False. True False A hormones half-life is the time required to remove 50% of the hormone from the bloodstream. True False Protein hormones are bound and are protected from breakdown by utilizing transport proteins in the bloodstream. True Lipid hormones have a longer half-life and slower clearance. True Lipid hormones are free (unbound) hormones and are not protected from breakdown. True False Enzymes of the blood, liver, and kidneys can easily breakdown protein hormones, therefore the hormones have a shorter half-life. True False A hormone’s signal is off” when they have served their “turned purpose. True False Lipid hormones have a shorter half-life, which means faster clearance from the blood. True False Protein hormones are hydrophobic and do not mix easily with plasma True False Lipid hormones are hydrophilic and mix easily with blood plasma
