Sort the phrases based on whether they describe or give an example of facilitated diffusion, active transport, or both.

1) Movement to area of lower concentration
2) Movement assisted by proteins
3) Requires energy
4) Sodium ion transport out of the cell
5) Glucose transport into cell
6) Movement across a membrane

1) Movement to area of lower concentration: facilitated diffusion  . It consists in the diffusion of a substance through a membrane in favor of its concentration gradient, that is to say that there is movement from an area of greater concentration to another of less concentration.

2) Movement assisted by proteins: both. In the facilitated diffusion the molecules must pass through membrane proteins. In active transport, the proteins involved are called pumps that normally use chemical energy.

3) Requires energy active transport: active transport makes use of energy for the movement of molecules because the movement is against a concentration gradient.

4) Sodium ion transport out of the cell: It is a type of active transport because it requires energy to allow movement against its concentration gradient, the ATP supplies the energy.

5) Glucose transport into cell: It is a type of diffusion facilitated through membrane proteins.

6) Movement across a membrane: both
