Question
The following statements concern the relationship between mitochondrial hydrogen ion concentration and energy storage as ATP during oxidative phosphorylation. Classify each statement as either accurate or inaccurate. Accurate statements Inaccurate statements The pH in the intermembrane space is higher than the pH in the mitochondrial matrix. ATP synthase uses energy from ATP to move H+ into the mitochondrial matrix. H^+ concentration is lower in the mitochondrial matrix than in the intermembrane space. Hydrogen ions cannot freely pass through the inner mitochondrial membrane. Energy is generated as a result of the difference in hydrogen ion concentration between the Intermembrane space and the cytoplasm. Oxidative phosphorylation relies on the H^+ gradient generated by the electron transport chain. ATP synthase uses energy from ATP to move H^+ into the mitochondrial matrix. Hydrogen ions cannot freely pass through the inner mitochondrial membrane.Explanation / Answer
Accurate statements: The pH in the intrmembrane spaceis higher than the pH in the mitochondrial matrix.
H+ concentration is lower in the mitochondrial matrix than in the intermembrane space
Energy is generated as a result of the difference in hydrogen ion concentration betweenthe intermembrane space and cytoplasm
Oxidative phosphorylation relies on the H+ gradient generated by the electron transport chain
Inaccurate statements: ATP synthase uses energy from ATP to moveH+ into the mitochondrial matrix
Hydrogen ions cannot freely pass through the inner mitochondrial membrane
