During the electron transport chain, protons (H+) are pumped from the mitochondrial matrix to the intermembrane space, leading to a higher concentration of protons in the intermembrane space. This results in a lower pH (more acidic) in the intermembrane space compared to the mitochondrial matrix, where the pH would be higher (more basic) due to the lower concentration of protons.
