Reabsorption of which substances is linked to na+ reabsorption in the proximal tubule? (choose all correct)
a. glucose
b. water
c. anions
d. urea

The correct answer is a glucose.

Explanation:

Proximal convulated tubule is an important part of the nephron of kidney.proximal convoluted tubule helps in the the reabsorption of Na+  from the glomerular filtrate along the  transport of glucose from the later.This type of transport is called co transport process.

   The co transport process is mediated by Na+ glucose symporter protein which uses the secondary active transport mechanism to facilitate the re absorption of Na+ along with glucose.

i think it is true since you can test the answer and can use observations to complete it.
