Q153 / 180 · NEET 2014 · Zoology

Which of the following causes an increase in sodium reabsorption in the distal convoluted tubule?

  • Correct answer
    A
    Increase in aldosterone levels
  • B
    Decrease in antidiuretic hormone levels
  • C
    Decrease in aldosterone levels
  • D
    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.

Hence, the correct answer is option: 'A'.
