Which statement is NOT true of the proton motive force (pmf)?
A) One component of the pmf is the chemical gradient of protons.
B) One component of the pmf is the charge gradient of protons.
C) Generation of the pmf in mitochondria requires succinate.
D) The pmf is generated by the electron transport chain in mitochondria.
E) The pmf drives ATP synthesis in mitochondria.

Question

Quizplus · Accepted Answer

Succinate is not required for the generation of the proton motive force (pmf) in mitochondria. The pmf is generated by the electron transport chain, which pumps protons across the inner mitochondrial membrane, creating a chemical and charge gradient of protons that drives ATP synthesis.
