Question

what type of transport is this?
how do you know?

Explanation:

Step1: Analyze the presence of ATP

The diagram shows ATP being converted to ADP + Pi. Active transport requires energy in the form of ATP.

Step2: Check the direction of ion movement

Na⁺ is moving out of the cell and K⁺ is moving into the cell against their concentration gradients. Active transport moves substances against their concentration gradients.

Answer:

This is active transport. We know this because ATP is being used (as shown by the conversion of ATP to ADP + Pi) and ions (Na⁺ and K⁺) are moving against their concentration gradients.
