Evidently, the ellipsoid vesicular structure in mitochondrial suspensions is caused by rupture and sealing (Picard et al. 2011). 1). 2). A series of enzyme complexes in the mitochondrial inner membrane (MIM) reduce oxygen to water and convert the combustion energy to ATP, which has a large negative free energy change of hydrolysis capable of driving otherwise endergonic reactions in coupled reaction networks. The mechanism for converting combustion energy is based on redoxdriven pumping of protons from the matrix space with a formation of transmembrane electrochemical potential across the MIM.

The copper centers of Complex IV are also visible in electron paramagnetic resonance spectrometry, but the method necessitates cryostat work at low temperatures and is applicable only for discrete samples (Pezeshk et al. 2001). 1 Succinate–Ubiquinone Oxidoreductase Although not having the capability of conserving redox energy as an electrochemical potential, succinate–ubiquinone oxidoreductase (Complex II, or succinate dehydrogenase [SDH]), a key enzyme of the TCA cycle, has been considered as a member of the respiratory chain for historical reasons, because it is an intrinsic membrane enzyme localized in the MIM.

The globular domain contains one covalently bound FAD molecule in subunit A and three iron– sulfur clusters in subunit B: a dinuclear (2Fe–2S), a trinuclear (3Fe–4S), and a tetranuclear (4Fe–4S). The iron–sulfur clusters form a 40 Å long electron transport chain from FAD to ubiquinone and heme B in the membrane domain. The heterodimeric anchoring domain is composed of a 140-residue large subunit (CybL) and a 103-residue small subunit (CybS). Together, they form a six-helix transmembrane bundle linked to a single central heme B560 and are tied together with other helices.
