Metabolism - ATP Synthesis, Mitochondria, Energy: In order to understand the mechanism by which the energy released during respiration is conserved as ATP, it is necessary to appreciate the structural features of mitochondria. These are organelles in ani
ATP is rightly referred to as a universal energy currency because changing ATP to ADP results in a fairly substantial free energy loss, which can be used to drive energetically unfavorable processes elsewhere. This is no different fundamentally from what happens in a test tube on the lab bench ...
Can externally applied ATP supply energy to active ion uptake mechanisms of intact plant cells? Aust J Plant Physiol 1, 211–220. Ma W, Smigel A, Tsai YC, Braam J, Berkowitz GA (2008). Innate immunity signaling: cytosolic Ca2+ elevation is linked to downstream nitric oxide generation ...
ABC exporters are thought to utilize the free energy from ATP-binding and hydrolysis at two nucleotide-binding domains (NBDs) to transport substrates via a translocation pathway that is formed by two membrane domains (MDs)9,10. In ABCB1, these four domains are fused on a single polypeptide, ...
Metabolism - ATP Formation, Enzymes, Energy: The second stage of glucose catabolism comprises reactions [6] through [10], in which a net gain of ATP is achieved through the oxidation of one of the triose phosphate compounds formed in step [5]. One molecu

In our particular case, ATP shifts the equilibrium between Au NP 1 and A away from the free energy minimum and continues to do so as long as its concentration remains above a certain threshold value. Although we have focused on transient signal generation, one can envision that the same ...
2024年7月11日,北京大学物理学院/定量生物学中心欧阳颀/李方廷团队在美国物理学会 (APS) 旗下期刊Physical Review Research发表了题为“Interplay between ATP and hydrolysis free energy in promoting and restraining biochemical switches” (DOI: 10.1103/PhysRevResearch.6.033050) 的研究论文,揭示了细胞内双稳态开关...
The postulated strictly linear descriptions of the rate dependence of oxidative phosphorylation in skeletal muscle on the free energy of ATP hydrolysis (delta GP) over the range of physiological steady states fail to harmonize with reported findings of identical basal respiration rates in mammalian muscl...
Furthermore, free ATP in cochlear fluids was close to that needed to cause hair cell depolarization in vitro. However, the source of ATP in the cochlear lymph fluids was unclear. Three possible ATP sources in the cochlea have been suggested, namely, marginal cells of the stria vascular9, ...
