Tubular secretion allows hydrogen ions, creatinine, and penicillin to be excreted in the distal convoluted tubule. How are these molecules moved across?

Question

Quizplus · Accepted Answer

Hydrogen ions, creatinine, and penicillin are all actively transported across the distal convoluted tubule membrane into the tubule for excretion. This process requires ATP and specific transport proteins in the membrane. Therefore, the correct choice is D, active transport.
