Question

A unique feature of the _____ is that these cells do NOT require insulin in order to transport glucose across the cell membrane.

1) liver cells
2) cells of the brain
3) muscle cells
4) pancreatic cells
5) cardiac cells

Answer 1

Cells of the brain do not require insulin to transport glucose across the cell membrane.

Step-by-step explanation:

The unique feature of cells of the brain is that they do NOT require insulin to transport glucose across the cell membrane.

Unlike other cells in the body, such as liver cells and muscle cells, which depend on insulin for glucose uptake, brain cells have a different group of carrier proteins called glucose transport proteins (GLUTs) that facilitate the transport of glucose across the cell membrane without the need for insulin.
