Identify the statements that accurately explain how hydrogen ion concentration relates to energy production in oxidative phosphorylation.
1) The Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated also maintained by the electron transport chain.
2) Hydrogen ions are vigorously transported out of the mitochondrial matrix.
3) Explain hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space
4) Define the pH in the intermembrane space is higher than the pH in the mitochondrial matrix.
5) Energy is generated as a result of the dissimilarity in hydrogen ion concentration between the mitochondrial matrix and the cytoplasm
6) ATP synthase offers energy in the form of ATP to actively transport H+ into the mitochondrial matrix.
