The majority of glucose 6-phosphate produced by the phosphorylation of glucose by ATP is metabolized to lactate and pyruvate in the glycolytic or Embden-Myerhof pathway. The direct nonmitochondrial oxidation of glucose 6-phosphate occurs by the pentose phosphate pathway (PPP), and the G6PD enzyme is the initial enzyme in this alternative route of glucose metabolism (Fig. 11-2). 

In Trichodesmium spp., maximum nitrogen fixation occurs at oxygen concentrations of 2.5-5% PAL. Under truly anaerobic conditions, the Embden-Myerhof... 

The two major metabolic pathways necessary for normal RBC metabolism are the hexose monophosphate shunt pathway, with its associated enzyme systems, and the Embden-Myerhof pathway of anaerobic glycolysis. The former is responsible primarily for maintaining Hgb in the rednced state and thns preventing the formation of methemoglobin, while the latter metabolizes glucose to lactic acid, which leads to adenosine triphosphate formation. 

Glycolytic flux through the Embden— Myerhof pathway is obviously decreased in hypoglycaemia, contributing to a decreased cerebral metabolic rate for glucose (CMRgl) (Abdul-Rahman and Siesjo, 1980). Transamination reactions occur, and the aspartate—glutamate transaminase reaction is shifted to the left (Fig. 3.1). 

Fig. 3.3 Krebs cycle in hypoglycemia. This fundamental metabolic pathway is altered during hypoglycemic coma. The Krebs cycle continues to turn, however short the glucose supply from Embden—Myerhof glycolysis is, due to a short circuit of metabolites across the circle by amino acid transamination...

Radiorespirometry was employed to study carbon metabolism during the growth of Streptomyces coelicolor A3(2) in a minimal medium, which permitted the production of 199 as the sole detectable secondary metabolite. A switch in the pattern of carbon metabolism from the Embden-Myerhof-Parnas pathway to the pentose phosphate pathway occurred during the period of slower growth in batch culture which immediately preceded entry into the stationary phase. This coincided with the period of production of 199. It was proposed that the biosynthesis of 199 is supported by the generation of NADPH during the latter part of the growth [220]. 

An analysis of the products of glucose fermentation by Lactobacillus caesi indicated that approximately 97 % of the total fermentation occurs via the Embden-Myerhof glycol3d ic cycle and the remaining 3% through an undefined path. ...
