Which of the following is true of aldosterone?
Aldosterone Increases the number of open Na channels on the apical
membrane of distal tubule cells
OAldosterone decreases Na- reabsorption and K+ secretion
Aldosterone binds to a g protein.coupled receptor
OAldosterone is secreted by the macula densa
( డరంకగంగంగt fndroesos in10 ౧umetr of Na• / x• ATT2sంs on the ap/cal mcm br ane

The hormone which has the opposite effect of aldosterone is:
O ANF which decreases Na+ reabsorption in the proximal tubule
ANF which increases Na+ reabsorption in the proximal tubule
ANF which increases Na+ reabsorption in the distal tubule
ANF which decreases Na+ reabsorption in the distal tubule
Eplerenone is a drug that blocks aldosterone function. Based on your knowledge of
aldosterone function, which of the following is the most likely result of taking this
drug?
O An increase in Na reabsorption in the distal tubules
OA decrease in K secretion in the distal tubules
An increase in antidiuretic hormone secretion
OAn increase in blood volume
None of the above would occur if aldosterone is blocked
