1.choose all that apply:
Which of the following parts of the kidney tubules can be
regulated by hormones
Bowman's capsule
Proximal tubule
Loop of Henle
Distal tubule
Collecting ducts
2. Choose all that apply:
Reabsorption of Na+...
occurs in all segments of the nephron except the descending loop
of Henle.
occurs at a constant rate in the proximal tubule and ascending
loop of Henle.
depends on active transport.
is stimulated by aldosterone in the distal tubule.
3. a vast majority of Na+ reabsorption that occurs in the
nephron depends on
the hormone aldosterone.
the hormone ADH (vasopressin).
unregulated primary active transport.
solvent drag.
4. the glucose in the urine is symptomatic of diabetes mellitis
because it is
diabetics have defective glucose carriers in the kidney
tubules.
diabetics do not produce enough ATP for adequate glucose
reabsorption.
the glucose concentration gradient in the tubules opposes
reabsorption.
the glucose carriers in the tubules reach their transport
maximum (Tmax) and are overwhelmed by the excess glucose.
