How does uniport transport compare with simple diffusion?

#Unit 2. Cellular Organization

  1. Similar to simple diffusion, uniport transport is nonspecific.

  2. Uniport transport is slower but more specific than simple diffusion.

  3. Uniport transport is much faster and more specific than simple diffusion.

  4. Simple diffusion is reversible but uniport transport is not.
