During reabsorption in the proximal convoluted tubule, most of the amino acids, glucose, Na⁺ ions, K⁺ ions, and Ca²⁺ ions are removed from the tubular fluid by ________ mechanisms. A)active transport B)counter transport C)osmotic D)passive transport

Question

Quizplus · Accepted Answer

Most of the substances mentioned in the question (amino acids, glucose, Na+, K+, Ca2+) are actively transported out of the tubular fluid and into the peritubular capillaries during reabsorption in the proximal convoluted tubule. This requires energy and is therefore an example of active transport.

During Reabsorption in the Proximal Convoluted Tubule, Most of the Amino
