Cells of the ________ System Require a Continuous Supply of Glucose

Question

Cells of the ________ system require a continuous supply of glucose.
A)muscular
B)respiratory
C)digestive
D)nervous

Accepted Answer

The nervous system requires a continuous supply of glucose because neurons (brain cells) rely almost exclusively on glucose for energy under normal conditions. Unlike other cells, neurons have a limited ability to store energy and are unable to switch to other energy sources efficiently, making a constant glucose supply crucial for their function.
