What is correct about the movement of substance across the membrane in facilitated diffusion?
Options
- AIt is an active transport.
- BIt doesn't cause transport of molecules from low concentration to high concentration.
- CIt is insensitive to inhibitors.
- DIt is a very specific transport.
Correct answer
D. It is a very specific transport.
Step-by-step solution
In facilitated diffusion special proteins help move substances across membranes along the concentration gradient without expenditure of energy. Facilitated diffusion is very specific, it allows cell to select substances for uptake. It is sensitive to inhibitors which react with protein side chains.
