C)Electron transport.
D)ATP → ADP.

Question

Quizplus · Accepted Answer

Secondary active transport relies on the use of an electrochemical gradient, typically an ion concentration gradient, established by primary active transport (which requires ATP). The energy stored in the electrochemical gradient is then used to transport other substances against their concentration gradient. Therefore, ion concentration gradient can serve as an energy source for secondary active transport. Light, electron transport, and the breakdown of ATP to ADP are not directly involved in secondary active transport.
