Primary and secondary active transport both A) generate ATP. B) are based on passive movement of Na⁺ ions. C) include the passive movement of glucose molecules. D) use ATP directly. E) can move solutes against their concentration gradients.

Question

Quizplus · Accepted Answer

Primary and secondary active transport are mechanisms that can move solutes against their concentration gradients, which means that they require energy input. While primary active transport directly uses ATP to transport solutes, secondary active transport harnesses the energy stored in electrochemical gradients to power the movement of other solutes. Both types of transport can move ions such as Na+ and K+, but they can also move other molecules such as glucose. However, neither process generates ATP or is based solely on the passive movement of ions.
