Question

Glucose is needed by all cells in order to do cellular respiration. How does glucose, a large molecule, enter cells without using cell energy?

a
via channel proteins using facilitated diffusion
b
by employing active transport
c
using proteins pumps and ATP
d
osmosis moving against the concentration gradient

Answer 1

The correct answer is:

**a. via channel proteins using facilitated diffusion**

Glucose, while a large molecule, can enter cells through facilitated diffusion. This process involves channel proteins or carrier proteins that help transport glucose across the cell membrane without the need for energy, as it moves down its concentration gradient.
