3How do molecules in the previous question diffuse across the membrane?
- Aactive transport
- Bfacilitated diffusion
- Cosmosis
- Dsimple diffusion
4What are two ways that active transport is different than facilitated diffusion?
- AActive transport requires energy
- BFacilitated diffusion requires energy
