Homeostasis and Endocrine System Exam
LATEST SUBMISSION GRADE
100%
1. Even though no food had entered her stomach, the smell and sight of food caused Jane’s point
stomach to secrete more acid. This is an example of:
antagonistic control
tonic control
negative control
feed-forward control
Correct
2. Jerry is a normal 24 year old male with an intracellular fluid (ICF) volume of 24 L. What is point
the volume of his plasma?
3L
9L
12 L
6L
Correct
3. In a normal female, plasma levels of the hormone cortisol are highest in the early morning point
and half maximal at 4:00 in the afternoon. This is an example of:
tonic control
antagonistic control
autocrine control
1/5
, circadian rhythm
Correct
4. Estrogen acts in the breast to increase the growth of the glands and the number of point
estrogen receptors in these cells. This is an example of:
positive feedback
negative feedback
antagonistic control
tonic control
Correct
5. Potassium ions in the _____ are in equilibrium with potassium ions in the _____. point
ECF; ICF
IVF; ISF
IVF; ICF
ISF; ICF
Correct
6. A membrane that is permeable only to water separates two solutions of glucose dissolved point
in water. On one side (A) the glucose concentration is 0.1 g/ml. On the other side (B) the
glucose is concentration is 0.6 g/ml. Initially the rate of water flow is:
zero (no flow in either direction)
more rapid from side A to side B
2/5
, more rapid from side B to side A
the same in both directions
Correct
7. Larry drank 2 cups of hypotonic soup. How did the water in the soup distribute into the point
intracellular (ICF) and extracellular (ECF) compartments?
net water movement from ICF to ECF but less than that seen with isotonic fluid
ingestion.
no change in water distribution between ICF and ECF.
water will distribute equally (1/2 and 1/2) between ICF and ECF.
net water movement from ECF to ICF greater than that seen with isotonic fluid
ingestion.
Correct
8. The single most important factor that determines whether a given cell can be regulated by point
the steroid hormone aldosterone is the presence in this cell of:
heat shock proteins
specific aldosterone receptors
active transporters for aldosterone
cAMP and ADP
Correct
9. In obesity related Type II diabetes, levels of the peptide hormone, insulin, are either point
normal or elevated, yet target cells are less sensitive to the binding of insulin. This
suggests that the target cells:
3/5
, have excess intracellular glucose
are impermeable to insulin
cannot convert insulin to an active form
have a defect in their receptor signaling pathway
Correct
10. What is the maximum transport rate (Tm ) of the carrier depicted below? point
20
10
4
8
Correct
11. When steroid hormones bind to their target cell receptors: point
membrane bound receptors are activated
4/5
