Question
A molecule that diffuses down a concentration gradient moves from a region of ______ concentration to a region of ______ concentration.
- High, low
- Low, high
- Active system, passive system
- Passive system, active system
Hint:
A molecule that diffuses down a concentration gradient moves from a region of high concentration to a region of less concentration.
The correct answer is: High, low
- Diffusion happens from a solution of higher concentration to a solution of less concentration.
- The concentration gradient will be from a high concentration to a less concentration.
- When the transport is against the concentration gradient, it will move accordingly.
