According to him, the energy is created in three stages: Glycolysis occurring outside mitochondria producing 10% of energy and citric acid cycle and electron transport chain occurring within mitochondria and producing 90% of energy.
We extracted the pathways in which at least three compounds changed significantly (p<0.05); these included the citric acid cycle, glycerophospholipid metabolism, cysteine metabolism, protein digestion and absorption, nicotinate and nicotinamide metabolism, purine metabolism, pentose phosphate metabolism, and polyamine metabolism pathways (Table 3).
After comparing differences in their metabolic processes, the lab found that the cancerous cells prefer to use sugars in the citric acid cycle, instead of making lactate, the more common route.
The citric acid cycle happens in mitochondria, and its function is to release stored energy.
For instance, they saw a marked increase in products of the citric acid cycle.
may be a symptom of poor function of Krebs citric acid cycle (KCA).
Furthermore, these organic acids have high gross energy values (Freitag, 2007) and are used in various metabolic processes for energy generation such as production of ATP in citric acid cycle (Diebold and Eidelsburger, 2006) and also serve as substrates in intermediary metabolism (Kirchgessner and Roth, 1988).
