Question

Quizplus · Accepted Answer

The proximal convoluted tubules are responsible for actively transporting ions, nutrients, and other substances from the filtrate back into the blood, which requires the use of ATP. This active transport accounts for about 6% of one's daily resting ATP and caloric consumption. The other structures listed do contribute to the overall process of urine formation, but they do not require as much active transport as the proximal convoluted tubules.
