Answer:

Sodium ions are pumped from a region of lower concentration to a region of higher concentration in the nerve cells of humans

Explanation:

Active transport is a kind of transport in which substances or molecules are moved from a region where they are in low concentration to a region where they are in high concentration. Active transport occurs against concentration gradient, hence, energy input in form of ATP is required.

Based on this description, the option that best ilustrates active transport is when: Sodium ions are pumped from a region of lower concentration to a region of higher concentration in the nerve cells of humans. The process will require energy to occur since sodium ions are pumped against concentration gradient.
