Question

In which part of the nephron are sodium and chloride ions actively reabsorbed?

Answer 1

Answer:

The correct answer is option C. loop of Henle.

Explanation:

The loop of Henle is the part of a nephron in the kidney, that starts from the proximal convoluted tubule or PCT to the distal convoluted tubule DCT. The major role of the loop of Henle is to build a concentration gradient in the kidney.

Sodium (Na+), chloride (Cl−) and potassium (K+) ions are reabsorbed by secondary active transport from the urine by a Na-K-Cl co-transporter. The electrical gradient and concentration gradient causes more reabsorption of calcium (Ca2+), magnesium (Mg2+) and Na+.

Thus, the correct answer is option C.

Answer 2

Hey there! Here is my answer.

B. Loop Henle

Reason: Well, let's keep it short and sweet, it ascends, also meaning to rise, go up, or increase in size!

Hope this helped!
