high to low concentration; no energy required

Cell transport in which material travel from low
to high concentration; energy required

Low

Sodium potassium pump

to engulf larger material

remove

Multiple Choice

The cellular process known as the sodium-potassium pump was discovered in the 1950s by Jens Christian Skou, a Danish scientist. This process is a form of active transport that moves three sodium ions to the outside of a cell for every two potassium ions that it moves into the cell. Which of these best explains why energy is needed for active transport?

• Ions are negatively charged.

• Ions are attached to large proteins.

• Ions are trapped inside the plasma membrane.

• Ions are moved against the concentration gradient.
