Distinguish between diffusion and active transport

Answer:

- In diffusion molecules move from a highly concentrated region to a lowly concentrated region, while in active transport molecules move from a lowly concentrated region to
a highly concentrated region.
- In diffusion molecules move along concentrated gradient while in active transport molecules move against concentrated gradient.
- No energy is required in diffusion while
energy is required in active transport.
- Active transport requires protein carrier molecules while protein carrier molecules are not required.
