Question

Quizplus · Accepted Answer

The proximal and distal tubules contain the most mitochondria among the different parts of the nephron. This is because these segments are responsible for active transport and reabsorption of ions and nutrients, which requires a lot of energy in the form of ATP produced by mitochondria. The other options do not have as high a concentration of mitochondria as the proximal and distal tubules.
