NADH molecules are formed from NAD+ during the first two phases: glycolysis and the Krebs cycle. Glycolysis Glycolysis is the first step in the breakdown of glucose in cellular metabolism. It consists of an energy-requiring phase and an energy-releasing phase. In the process of glycolysis, ...
Glycolysis promotes the increase of carbon flux into the oxidized pentose phosphate pathway, thus accelerating the production of reactive oxygen species (ROS) in M1 macrophages [27], which is further facilitated by pro-inflammatory metabolites. M1 TAMs continuously accumulate succinate during the ...
Furthermore, members of the new phylum have the complete glycolysis pathway and may produce acetate, lactate, and alcohol as fermentation products (Fig.5d). Whereafter, acetyl-CoA may be produced by catalysis of pyruvate ferredoxin oxidoreductase (porin 12 genomes) and 2-oxoglutarate ferredoxin oxido...
It has been suggested that potential alterations observed in ES can be summarized by the following: (1) active aerobic glycolysis driven by the activation of LDH and attenuated ME and MDH; (2) decreased PDHK activity leading to activated PDH, causing a shift to the TCA cycle; and 3) ...
whereas metabolites determine the polarization of their functional phenotype [100]. During the anti-inflammatory process of M1 TAMs, lactate accumulation occurs due to increased glycolysis and the Warburg effect. It has been shown that lactate and lactylation exert an inducing effect on the polarizati...
Carbon sources were categorized into those introduced at the upper part of glycolysis (Group A sources) and those entering at other nodes of the metabolic network (Group B sources). Prioritised carbon utilization occurs among Group A sources, and usually the one that supports higher growth rate ...

coli. Manipulation of the rate-limiting reaction catalyzed by aspA enables adjustment of the flux in cataplerosis involving the pckA- and maeB-mediated pathways. This in turn modulates the flux distribution between glycolysis and gluconeogenesis. As exemplified by the ethanol production, this strategy ...
Sugars and acids are continually synthesised through respiratory metabolic processes including glycolysis, the citric acid cycle and mitochondrial electron transport chain (Fernie et al.2004). The products of these are involved in many downstream reactions. The building blocks of VOCs include sugars, ami...
while excessive cytokine release favors persistent infections in these high-risk subjects [64]. Hyperglycemia, a key hallmark of T2DM which frequently accompanies obesity, may lead alone to significant alterations in macrophage function. In patients with diabetes, hyperglycemia and glycolysis may bolster ...
