In rat models of mammary carcinogenesis, the highest incidence of carcinomas occurs when the animals are exposed to carcinogens during puberty (typically postnatal day 50). Gene expression analysis of rat mammary gland in Sprague-Dawley rats revealed a consistent down-regulation of Krebs cycle genes...

Citrate has an intense effect on the acid-base balance as well, if fully metabolized through the Krebs cycle, due to the production of bicarbonate. Even more severely ill patients, such as those with liver dysfunction, may be treated with RCA without severe complications, because modern machines...

The glucose moleculeis the primary fuel for cellular respiration. Without it, the entire process would not be able to start because there would be no pyruvate for use in the Krebs cycle. How does cellular respiration create water? The electron transport chain is the third and final step of ...
What process does yeast use to produce ethanol for automobile fuel from corn? (a) Anaerobic respiration (b) Fermentation (c) The Krebs cycle (d) Oxidation (e) Photosynthesis. What is the difference between fermentation and biosynthesis?
Krebs Cycle The second step of cellular respiration is called the Krebs Cycle, which is also known as the citric acid cycle or the tricarboxylic acid (TCA) cycle. This stage takes place in the matrix of a cell's mitochondria. During the continuous Krebs Cycle, energy is transferred to two...
Ketogenesis is an alternative pathway for hepatic use of NEFA when complete oxidation of NEFA in the Krebs cycle, in case of oxaloacetate shortage, is not possible (Drackley, 1999). The almost absent correlations between mobilization of AAT mass and blood BHB concentrations in the FCP indicate ...
Because BCAAs are converted to CoA compounds and used for energy generation via the Krebs cycle, they are implicated in mitochondrial activation. In our analysis, we found a novel BCAA fasting marker, ketovaline, in addition to isoleucine, keto(iso)leucine, leucine, and valine, which were ...
This phenotype was not due to a change in mitochondrial mass or number, but rather due to decreased mitochondrial function, as it could be rescued by inhibition of pyruvate dehydrogenase kinase 4 (PDK4), which diverts pyruvate from the Krebs cycle to the production of lactate [64]. Further...
