WITH CORRECT ANSWERS
Hormones are _____. - ANSWER-chemical signals between cells, transported in blood
or hemolymph
The hormone epinephrine causes opposite effects in two populations of target cells
because _____. - ANSWER-each set of target cells has different receptor-transduction
mechanisms
Oxytocin secretion and milk release from the mammary glands of lactating female
mammals are initiated by _____. - ANSWER-the physical sensation of the baby sucking
at the nipple
In their mechanism of action, a difference between lipid-soluble and water-soluble
hormones is that _____. - ANSWER-lipid-soluble hormones bind to an intracellular
receptor and this hormone-receptor complex binds to DNA
Jet lag occurs when a person moves rapidly from one time zone to another, causing
conflict between the body's biological rhythm and the new cycle of light and dark. Some
scientists suspect that jet lag may result from disruption of the daily cycle of secretion of
the hormone known as _____. - ANSWER-melatonin
Which category of signal exerts its effects on target cells by binding to membrane-
bound receptor proteins? - ANSWER-neurohormones
Different body cells can respond differently to the same peptide hormones because -
ANSWER-a target cell's response is determined by the components of its signal
transduction pathways.
The endocrine glands include the - ANSWER-parathyroid glands.
Testosterone is an example of - ANSWER-an androgen.
A cell with membrane-bound proteins that selectively bind a specific hormone is called
that hormone's - ANSWER-target cell
The counter-regulatory functions of the pancreas refer to the fact that it _____. -
ANSWER-releases one hormone that reduces glucose levels in the blood and another
that increases them
