While all active transport requires energy, the source of that energy distinguishes the two main types: Active transport: primary & secondary overview (article)

The general cycle of a primary active transport pump involves several key steps:

Beyond the sodium-potassium pump, other active transport devices run your life:

This pump is essential for maintaining the resting membrane potential in animal cells (crucial for nerve signals and muscle contractions).

While there are many types of pumps, these three are the most critical for general biology students to understand.
