Which of the following causes an increase in sodium reabsorption in the distal convoluted tubule?
Which of the following causes an increase in sodium reabsorption in the distal convoluted tubule?
Increase in aldosterone levels
Decrease in antidiuretic hormone levels
Decrease in aldosterone levels
Increase in antidiuretic hormone levels
Solution
Sodium absorption by the distal tubule is mediated by the hormone aldosterone. Aldosterone increases sodium reabsorption. Aldosterone is secreted by zona glomerulosa of adrenal cortex and also known as salt retaining hormone.
