Using information from the diagram, state one reason why the movement in the third image represents active transport

A protein or ion has passed through the "pump" or carrier proteins and move within the cell.

Nvm short and sweet ;)

Further info..

To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. With the exception of ions, small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive changes. Much of a cell’s supply of metabolic energy may be spent maintaining these processes. Because active transport mechanisms depend on cellular metabolism for energy, they are sensitive to many metabolic poisons that interfere with the supply of ATP.

hey, what do you need . just post the question and i may be able to you : )

2%? i tried finding the exact sorry if it's not 100% correct ; -;
