In this reaction, 1 molecule of 'H+' is translocated from mitochondrial intermembrane space to mitochondrial matrix.

This reaction takes place in the 'mitochondrial inner membrane' and is mediated by the 'hydrogen ion transporter activity' of 'UCP dimer' (Echtay et al. 2002a, Echtay et al. 2002b).
