Which of the following statements about the electron transport chain in cell respiration is CORRECT?

A. Electrons move from NADH to a chain of proteins with lower electronegativities.
B. The electron transport chain of proteins uses ATP to pump H+ across the inner mitochondria membrane against its electrochemical gradient.
C. The loss in free energy of the electron initially donated by NADH is used to transport H+ across the inner mitochondrial membrane against its electrochemical gradient.
D. The electron transport chain of proteins contains pores that are leaky to H+.
E. The ATP synthase pump generates a H+ gradient across the inner mitochondrial membrane.
