Because of the great deal of active transport that occurs here, the of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.

Because of the great deal of active transport that occurs here, the proximal convulated tubules of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.

Explanation:

Proximal convulated tubule is responsible for transport of a very large number of substances mentioned below :

Transporters include :

As a large number or transporters are present in the PCT , large amouny of ATP is cleaved here, and about 6% of daily resting ATP and caloric consumption occurs.

i believe the answer is a or 1
