24. In purine nucleotide biosynthesis the most important direct precursor is (A) Adenosine, (B) Inosine, (C) Guanine, (D) Uridine, (E) Xanthosine. 25. The reaction of deoxynucleotide synthesis is (A) oxidation, (B) phosphorylation, (C) reduction, (D) ...
To demonstrate that Petri nets are indeed suitable for simulating metabolic pathways, the glycolysis and citric acid cycle are selected as well-understood examples of enzymatic reaction chains (metabolic pathways). The paper discusses the steps that lead from gaining necessary knowledge about the ...
Such a configuration offers potential advantages over the indirect approach in terms of thermal coupling to improve the electrochemical reaction kinetics as well as the possibility to use cheaper and more abundant catalysts due to the 10–100× lower cur- rent densities4. Despite the impressive ...
stimulation of citric acid cycle and uncoupling effect on oxidative phosphorylation (probably caused by flavonoid effect on mitochondrial respiration and direct inhibition of ATP-synthase). Furthermore, low quercetin concentrations (25μM) stimulated oxygen uptake, while its high concentrations (50–300μ...
