Question

Why does glucose use facilitated diffusion?

Answer 1

Facilitated diffusion:

1. The passive transport of molecules down the concentration gradient is known as facilitated diffusion.
2. It is a selective process, meaning that only specific molecules and ions can pass through the membrane.
3. However, it blocks the passage of other molecules across the membrane.
4. Large molecules make it challenging for glucose to diffuse across a membrane.
5. As a result, it moves down the concentration gradient through facilitated diffusion across membranes.
6. The glucose is bound by the carrier protein at the membrane, which changes its structure to make it transportable.
