Like all cells, the neurons' internal organization dictates its function. Neurons have relatively many mitochondria, an extensive network of rough endoplasmic reticulum and many clusters of ribosomes. These cellular features indicate all of the following EXCEPT___________ .
A) neurons must meet a high demand for ATP
B) neurons produce many proteins
C) neurons have stable, relatively unchanging internal environments
D) neurons have a relatively high consumption of oxygen

Question

Quizplus · Accepted Answer

The presence of a large network of rough endoplasmic reticulum and many clusters of ribosomes suggests that neurons produce many proteins, which is supported by choice B. The abundance of mitochondria and high oxygen consumption supports choice A and D. Therefore, the only option not supported by the given information is choice C, which suggests stable and unchanging internal environments, whereas neurons are dynamically active cells that constantly respond to changes in their environment.
