In distal convoluted tubule of the nephrons

A

Na reabsorption requires energy

B

Secretion of K ions does not require energy

C

Water reabsorption requires energy

D

Ammonia is secreted

Text Solution

Verified by Experts

The correct Answer is:
A

The distal convoluted tubule reabsorbs water by osmosis and actively reabsorb sodium from the filtrate under the influence of adrenal hormone aldosterone which makes their walls permeable to ions.
