The intermembrane space of a mitochondrion has a lower pH than the matrix due to the presence of proton pumps in the inner membrane that pump protons from the matrix to the intermembrane space, creating an electrochemical gradient that drives ATP synthesis. This gradient leads to a build-up of protons in the intermembrane space, resulting in a lower pH compared to the matrix.
