BSC2086: Ch17:The Endocrine System Questions With
Complete Solutions
A hormone controls the concentration of some substance in the
circulatory system. A tumor begins to produce that substance i
large amounts in an uncontrolled fashion. The secretion rate for
the hormone would: Correct Answers b. decrease by negative
feedback
A hormone is secreted in large amounts, modified by the liver,
and excreted by the kidney rapidly, thus making its half-life very
short. A patient that has liver and kidney disease would see this
effect: Correct Answers a. the hormone is not modified and
excreted rapidly
b. increases blood levels of this hormone
c. concentration remains high for a longer time
e. a, b and c
A person with no ADH secretion (diabetes insipidus) might have
symptoms including these: Correct Answers c. extreme thirst
and dehydration
Aldosterone: Correct Answers c. increases sodium
concentration in the blood
Anti-inflammatory drugs such as aspirin, inhibit prostaglandin
synthesis and as a result, reduce inflammation and pain. Correct
Answers True
, Chemical signals that are secrete into the environment and
modify the behavior and physiology of the other individuals are
called this: Correct Answers b. pheromones
Down-regulation occurs because of this: Correct Answers a.
both hormone and receptor are taken into the cell by
phagocytosis
b. receptor molecules are degraded more quickly
c. there is a decrease in the rate of receptor synthesis
d. al of these
Estrogen, progesterone, testosterone, and glucocorticoids are all
examples of this: Correct Answers e. steroids
Given these characteristics:
1. amplitude-modulated signals
2. all-or-none response
3. usually slower response
4. effects usually more generally distributed
List the characteristics that apply to the endocrine system when
compared to the nervous system. Correct Answers c. 1,3,4
Given these events:
1. activation of cAMP
2. activation of genes
3. enzyme activity altered
These events can occur when a hormone binds to an intracellular
hormone receptor: Correct Answers c. 2,3
