Question

1) 1) Energy is generated as a result of the difference in hydrogen ion concentration between the intermembrane space and the cytoplasm.
2) The pH in the intermembrane space is higher than the pH in the mitochondrial matrix.
3) Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
4) Hydrogen ions cannot freely pass through the inner mitochondrial membrane.
5) ATP synthase provides energy in the form of ATP to actively transport H+ into the mitochondrial matrix.
6) oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the ETC.

There are three correct answers.
