Solution

The correct option is A Perimitochondrial space
In respiration, protons accumulate in the intermembrane space of the mitochondria (perimitochondrial space), when electrons move through the ETS. The protons accumulated form the Proton Motive Force (PMF) which facilitates the process of chemiosmosis for the generation of ATP.
