Identify the statements that accurately describe how hydrogen ion concentration

Question

Identify the statements that accurately describe how hydrogen ion concentration relates to energy production in oxidative phosphorylation. ATP synthase provides energy in the form of ATP to actively transport H^+ into the mitochondrial matrix. Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space. Hydrogen ions are actively transported out of the mitochondrial matrix. Energy is generated as a result of the difference in hydrogen ion concentration between the mitochondrial matrix and the cytoplasm. Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain. The pH in the mitochondrial matrix is lower than the pH in the intermembrane space.

Explanation / Answer

1. Hydrogen ion concentration is lower in mitochondrial matrix than in the intermembrane space.

2. oxydative phosphorylation relies on the hydrogen ion concentration gradient generated and aintained by the electron transport chain.

3. The pH in the mitochondrial matrix is lower than the pH in the intermembrane space.
