What are the driving force (energetic) costs for the ATP-ADP translocase?

Question

Quizplus · Accepted Answer

The driving force (energetic) cost for the ATP-ADP translocase is the membrane potential generated by electron transport. This generates a negative electrochemical potential, driving the movement of positively charged ATP into the mitochondria in exchange for negatively charged ADP. Entropy and the concentration gradient of ATP are not significant drivers for the ATP-ADP translocase. Active transport by Na+-K+ ATPase is not directly involved in the ATP-ADP translocase.
