Quizplus · Accepted Answer

Active transport requires the input of energy, typically in the form of ATP, to move molecules or ions across a cell membrane. In this case, the CFTR receptor actively transports chloride ions out of the cell, indicating that energy in the form of ATP is necessary for this process. Therefore, the best choice is D: a reaction requiring the input of energy (ATP).
