The parts of the nephron whose epithelial cells contain the most mitochondria are the
A) renal corpuscle and distal convoluted tubule.
B) proximal and distal convoluted tubules.
C) thin segment and glomerular capsule.
D) vasa recta and collecting tubules.

Question

Quizplus · Accepted Answer

The proximal and distal convoluted tubules have the most mitochondria in their epithelial cells, as these cells are responsible for active transport and reabsorption of ions and nutrients. Mitochondria generate ATP, which is necessary for these energy-intensive processes. The other options either contain thinner epithelial cells (thin segment and glomerular capsule) or are not involved in active transport (vasa recta and collecting tubules).
