Jerry is a normal 24 year old male with an intracellular fluid (ICF) volume of 24L. What is the volume of his plasma? |
3L |
|
|
In a normal female, plasma levels of the hormone, cortisol are highest early in the morning and half maximal at 4 in the afternoon. This is an example of |
circadian rhythm |
|

A membrane that is permeable only to water separates two solutions of glucose dissolved in water. On one side (A) the glucose concentration is 0.1g/mL. On the other side (B) the glucose is concentration is 0.6g/mL. Initially the rate of water flow is |
more rapid from side A to side B |
|
|
Larry drank 2 cups of hypnotic soup. How did the water in the soup distribute into the intracellular (ICF) and extracellular (ECF) compartments? |
net water movement from ECF to ICF greater than that seen with isotonic fluid ingestion |
|
|
The single most important factor that determines whether a given cell can be regulated by the steroid hormone aldosterone is the presence in this cell of |
specific aldosterone receptors |
|
|
In obesity related Type II diabetes, levels of the peptide hormone, insulin, are either normal or elevated, yet target cells are less sensitive to the binding of insulin. This suggests that the target cells |
have a defect in their receptor signaling pathway |
|
What is the maximum transport rate (Tm) of the carrier depicted here? |
8 |
|
|
When steroid hormones bind to their target cell receptors |
transcription of DNA is stimulated |
|
|
Even though no food had entered her stomach, the smell and sight of food caused Jane's stomach to secrete more acid. This is an example of
|
feed-forward control
|
