Recently the F0 portion of the bovine mitochondrial F1F0-ATP synthase was shown to contain eight ‘c’ subunits (n = 8). This surprised many in the field, as previously, the only other mitochondrial F0 (for yeast) was shown to have ten ‘c’ subunits. The metabolic implications of ‘c’ subunit copy number explored in this paper lead to several surprising conclusions: (1) Aerobically respiring E. coli (n = 10) and animal mitochondria (n = 8) both have very high F1F0 thermodynamic efficiencies of ≈90… 
Energy coupling mechanism of FO in a rotary ATP synthase: a model update
In nearly all living cells, rotary ATP synthases of the F1FO family are essential to inter-conversing of energy between the transmembrane electrochemical potential and the ATP form (Boyer 1997).
The c-Ring of the F1FO-ATP Synthase: Facts and Perspectives
The simple c-ring structure not only allows the F1FO-ATP synthase to perform the two opposite tasks of molecular machine of cell life and death, but it also amplifies the enzyme’s potential role as a drug target.

Optimization of ATP Synthase c–Rings for Oxygenic Photosynthesis
Numerical kinetic simulations of the energetics of chloroplast photosynthetic reactions with altered c–ring size predicts the energy storage of pmf and its effects on the photochemical reaction centers strongly support this hypothesis, suggesting that, despite the low efficiency and suboptimal ATP/NADPH ratio, a high H+/ATP is favored to avoid photodamage.

It is concluded that mitochondria are capable of effectively utilizing the environmental heat energy with TELP for the synthesis of ATP, i.e., it can lock heat energy into the chemical form of energy for cellular functions.
Thermodynamics and kinetics of the FoF1-ATPase: application of the probability isotherm
Numerical solution of the Rate Isotherm suggests that the experimental results may be more consistent with damage to the enzyme caused by its isolation from the biomembrane and its experimental fixation, resulting in non-physiological friction within the enzyme's rotary mechanism.
A low phosphorylation potential in the acetogen Acetobacterium woodii reflects its lifestyle at the thermodynamic edge of life
The anaerobic, acetogenic bacterium Acetobacterium woodii grows on hydrogen and carbon dioxide and uses the Wood–Ljungdahl pathway to fix carbon but also to synthesize ATP. The free energy change of


Stoichiometry of proton translocation by respiratory complex I and its mechanistic implications
In a rough mechanistic model, a concerted proton translocation mechanism in the three homologous and tightly packed antiporter-like subunits L, M, and N of the proton-translocating membrane domain of complex I is suggested.
The thermodynamic H+/ATP ratios of the H+-ATPsynthases from chloroplasts and Escherichia coli
The thermodynamic H+/ATP ratio is the same for both enzymes and that it is different from the subunit stoichiometric ratio, indicating that the energy balance of all cells is maintained.
Engineering rotor ring stoichiometries in the ATP synthase
The high degree of compliance in the architecture of the ATP synthase rotor offers a rationale for the natural diversity of c-ring stoichiometries, which likely reflect adaptations to specific bioenergetic demands.
The c-ring stoichiometry of ATP synthase is adapted to cell physiological requirements of alkaliphilic Bacillus pseudofirmus OF4
The data indicate a direct connection between the precisely adapted ATP synthase c-ring stoichiometry and its ion-to-ATP ratio on cell physiology, and also demonstrate the bioenergetic challenges and evolutionary adaptation strategies of extremophiles.
Bioenergetic cost of making an adenosine triphosphate molecule in animal mitochondria
In fungi, eubacteria, and plant chloroplasts, ring sizes of c10–c15 subunits have been observed, implying that these enzymes need 3.3–5 protons to make each ATP, but until now no higher eukaryote has been examined.

There are tales of P/O battles at conferences in the 1950s. P/O is the number of ATP molecules synthesized by oxidative phosphorylation for each pair of electrons (hence, not P/O2) passing from a
The Oligomeric State of c Rings from Cyanobacterial F-ATP Synthases Varies from 13 to 15
This systematic study of the c-ring stoichiometries suggests that variability of c- ring sizes might represent an adaptation of the individual cyanobacterial species to their particular environmental and physiological conditions.
Essentials for ATP synthesis by F1F0 ATP synthases.
The majority of cellular energy in the form of adenosine triphosphate (ATP) is synthesized by the ubiquitous F(1)F(0) ATP synthase, which derives from an electrochemical proton gradient, which drives rotation of membranous F(0).
