From the foregoing considerations, the energy-linked transhydrogenase reaction emerges
as a powerful and flexible element in the network of redox and energy interrelationships that …

Significance: Proton-translocating NAD (P)+ transhydrogenase, also known as nicotinamide
nucleotide transhydrogenase (NNT), catalyzes a reversible reaction coupling the …

The Pi⇄ HOH exchange reaction of oxidative phosphorylation is considerably less sensitive
to uncouplers than the Pi⇄ ATP and ATP⇄ HOH exchanges. The uncoupler-insensitive Pi⇄ …

In 1961, two concepts of energy coupling were published, one by Mitchell I and the other by
Williams z, both dealing with the transfer of charges (electrons, H÷, OH-) in biological energy …

Publisher Summary This chapter discusses the mechanisms by which bacterial membranes
generate useful energy and perform the work of chemical synthesis, transport, and …

The concept is developed according to which Na+, like H+, can play the role of a coupling
ion in energy‐transducing biomembranes. This idea is based on observations that (i) Na+ …

Compensatory changes in energy expenditure occur in response to positive and negative
energy balance, but the underlying mechanism remains unclear. Under low energy demand …

The NADH dehydrogenase region of the respiratory chain has been reviewed quite
extensively during the last few years (see text for references), and since no real …
