Secondary active transport across a membrane refers to

Question

Quizplus · Accepted Answer

Secondary active transport involves the movement of a molecule against its concentration gradient, but unlike primary active transport, it is not directly powered by ATP. Instead, it relies on the energy stored in an ion gradient that has been established by a different transporter. This is the case in option A, making it the correct choice. Option B describes primary active transport, option C describes simple diffusion, option D is not a valid description of any transport process, and option E is not a valid answer.
