Which of the following transporters mediates primary active transport when transporting the solutes in the directions indicated? The concentration of both solutes (shown as small circles and squares) is higher outside of the cell.

Question

Quizplus · Accepted Answer

In secondary active transport, a transporter can use the energy from the transport of one solute down its electrochemical gradient to drive the transport of another solute against its electrochemical gradient. However, pumping all of the solutes against their electrochemical gradients requires an external energy source and is known as primary active transport.
