The inner mitochondrial membrane is damaged, and it becomes increasingly permeable to hydrogen ions. Which of the following statements IS NOT true. The H+ gradient stored in the matrix created by the electron transport chain dissipates when H+ ions diffuse into the inner mitochondrial membrane space. Complex I, II, III and IV are still able to pump H+ into the inner mitochondrial membrane space due to the oxidation of NADH and FADH2. The H+ ions pumped into the inner mitochondrial membrane space are not efficiently used by ATP synthase to generate ATP. As a result, the production of ATP for every molecule of pyruvate that enters the mitochondrion is reduced.

Question
The inner mitochondrial membrane is damaged, and it becomes increasingly
permeable to hydrogen ions. Which of the following statements IS NOT true.
The H+ gradient stored in the matrix created by the electron transport chain
dissipates when H+ ions diffuse into the inner mitochondrial membrane space.
Complex I, II, IIl and IV are still able to pump H+ into the inner mitochondrial
membrane space due to the oxidation of NADH and FADH2.
The H+ ions pumped into the inner mitochondrial membrane space are not
efficiently used by ATP synthase to generate ATP.
As a result, the production of ATP for every molecule of pyruvate that enters the
mitochondrion is reduced.
All of these statements are true.
