Correct Answers (Grade A+)
Question 1: Secretions of the pineal gland: include vasopressin. may be involved with development of
the immune system. may inhibit reproductive functions. increase the release of GnRH from the
hypothalamus. decrease the tendency to sleep.
Answer: may inhibit reproductive functions.
Question 2: A person with insulin-dependent diabetes mellitus (IDDM) forgets to take their insulin.
This causes: alkalosis. hypoglycemia. decreased urine production. decreased appetite. hyperglycemia.
Answer: hyperglycemia.
Question 3: Growth hormone: increases amino acid uptake in cells. decreases the use of fat as an energy
source. decreases the synthesis and storage of glycogen. increases the use of glucose for energy.
facilitates the uptake of glucose by cells.
Answer: increases amino acid uptake in cells.
Question 4: The posterior pituitary: has a direct connection with neurons of the hypothalamus. is
controlled by releasing hormones produced in the hypothalamus. produces hormones that regulate
other endocrine glands. stores lipotropins. is not related to fluid balance in the body.
Answer: has a direct connection with neurons of the hypothalamus.

individual nutrients. Regulates the rate of metabolism. Regulates the levels of nutrients such as glucose
in the blood.
Answer: Initiation of skeletal muscle action potentials.

, Question 8: Urine volume ____ when ADH (antidiuretic hormone) secretion decreases. increases
decreases is not affected declines None of these choices are correct.
Answer: increases
Question 9: John Smith works outdoors in the winter at a ski resort. His thyroid hormone levels are
lower in the winter to conserve body heat. higher in the winter to increase body temperature. lowered
in the summer after his job to decrease body temperature. increased in the summer after his job to
increase body temperature. unaffected by his job.
Answer: higher in the winter to increase body temperature.
Question 10: Thyroid hormone interacts with its target tissue by using the intracellular mediator
system. binding to a membrane bound receptor. increasing iodine uptake in the target cells. releasing
thyroglobulin. binding to receptor molecules in the nucleus.
Answer: binding to receptor molecules in the nucleus.
Question 11: Arrange the following events in proper sequence: (1) The activating hormone interacts
with a membrane-bound receptor. (2) Cyclic AMP causes the cell to carry out a function characteristic
for that specific hormone. (3) Adenylyl cyclase catalyzes the transformation of ATP to cyclic AMP. (4)
Adenylyl cyclase is activated. 1, 2, 3, 4 1, 4, 3, 2 3, 4, 2, 1 1, 3, 2, 4 1, 3, 4, 2
Answer: 1, 4, 3, 2
Question 12: When a few intracellular mediator molecules activate several enzymes, and each of these
activated enzymes activate still other enzymes, the hormone has initiated a cascade effect. a double loop
effect. a protein kinase effect. a cyclic effect. a negative feedback cycle.
Answer: a cascade effect.
Question 13: When a hormone binds to a membrane-bound receptor, membrane channels are
destroyed. cyclic GMP might be produced to act as an intracellular mediator. the nucleus is
phosphorylated to prevent G-protein activation. messenger RNA is formed. cellular DNA is altered.
Answer: cyclic GMP might be produced to act as an intracellular mediator.

events that follow in correct sequence. (1) alpha subunit-GTP complex alters cell activity (2) GTP binds
to the alpha subunit replacing GDP (3) G-protein subunits separate from the receptor (4) alpha subunit
separates from other two subunits (5) G-protein subunits bind to the receptor 5, 2, 3, 4, 1 4, 2, 1, 3, 5 5,
