With respect to their relative pH $,$ how do the cytosol, intermembrane space of the mitochondria, and the mitochondrial matrix compare?

$$ pH cytosol $>pH$ of the intermembrane space $=pH$ of the mitochondrial matrix

pH of the mitochondrial matrix $=pH>pH>pH$ cytosol

$pHof$ the mitochondrial matrix $>pH$ cytosol $>pHof$ the intermembrane space $of$ the mitochondrial matrix cytosol

$pHof$ the mitochondrial matrix $>pH$ cytosol $>pHof$ the intermembrane space cytosol $=pHof$ the intermembrane space

$pHof$ the intermembrane space $of$ the mitochondrial matrix cytosol

$pHof$ the mitochondrial matrix $>pH$ cytosol $>pHof$ the intermembrane space
