Fig. 2. Turbo design of glycolysis. Panel A shows the turbo design of glycolysis, where ATP is invested in the activity of HK and PFK at the beginning of the pathway and surplus ATP is produced downstream in the PGK and PYK catalysed reactions. This design may have the dangerous result ...
Let's use 32 as the number of ATP produced per glucose's aerobic catabolism. Now, what would the ATP yield be, in aerobic catabolism, for the processing of dihydroxyacetone phosphate? A. 32 B. 16 C. 1 Inside an active mitochondrion, most electrons follow which pathway? a. glycolysis, NA...
ATP can also be produced by theadenylate kinasereaction, which catalyzes the conversion of two adenosine diphosphate (ADP) molecules into one ATP and one adenosine monophosphate (AMP); however itsclinical significanceis limited. The oxidative phosphorylation system (Fig. 151.2), present in the inner...
In the oxidative system the resynthesis of ATP happens at a much slower rate, but we can maximize the number of ATPs produced, yielding us with the highest amount of energy. Lactate sometimesgets an undeserving bad wrap.Many people mistakenly associate an increase in lactate with an increase i...

The lactate produced by glycolysis of tumor cells has also been proved to inhibit the function of various immune cells, and is also related to the resistance of tumor immunotherapy [5, 6]. Given the crucial role of tumor glycolysis in its genesis, development, and treatment, it is necessary...
In general, naive CD8+T cells rely mainly on ATP produced by mitochondrial oxidative phosphorylation (OXPHOS) for survival [23]. Meanwhile, to prevent atrophy of quiescent T cells, IL-7 signaling mediates the activation of protein kinase B (AKT) through signal transducer and activator of transcri...
Oncogenic KRAS expression generates a metabolic dependency on aerobic glycolysis, known as the Warburg effect. We report an effect of increased glycolytic flux that feeds into glycosphingolipid biosynthesis and is directly linked to KRAS oncogenic functi
To ensure that tumour cells entrap adequate glucose, this VDAC-HK interaction inhibits the negative feedback regulation of G6P. The VDAC-HK interaction also gives HK direct access to ATP produced by mitochondria and prevents BAX that binds to VDAC in normal cells from attaching to VDAC [44, ...
Aliquots of day 7 CFU-Es (1 × 105 cells) were then cultured in phase II medium. During phaseII of the culture, no significant differences were observed in the cell number of day 7 CFU-Es cultured for up to 48hours between the 5% and 21% O2 conditions (Fig.1B), whereas the ...
