  2. Pasteur effect - Wikipedia

    en.wikipedia.org/wiki/Pasteur_effect

    If the concentration of oxygen increases, pyruvate is instead converted to acetyl CoA, used in the citric acid cycle, and undergoes oxidative phosphorylation. Per glucose, 10 NADH and 2 FADH 2 are produced in cellular respiration for a significant amount of proton pumping to produce a proton gradient utilized by ATP Synthase. While the exact ...

  3. Crabtree effect - Wikipedia

    en.wikipedia.org/wiki/Crabtree_effect

    The Crabtree effect, named after the English biochemist Herbert Grace Crabtree, [1] describes the phenomenon whereby the yeast, Saccharomyces cerevisiae, produces ethanol (alcohol) in aerobic conditions at high external glucose concentrations rather than producing biomass via the tricarboxylic acid (TCA) cycle, the usual process occurring aerobically in most yeasts e.g. Kluyveromyces spp. [2 ...

  4. Phosphorylation - Wikipedia

    en.wikipedia.org/wiki/Phosphorylation

    Glycogen is a long-term store of glucose produced by the cells of the liver. In the liver, the synthesis of glycogen is directly correlated with blood glucose concentration. High blood glucose concentration causes an increase in intracellular levels of glucose 6-phosphate in the liver, skeletal muscle, and fat tissue.

  5. Blood sugar level - Wikipedia

    en.wikipedia.org/wiki/Blood_sugar_level

    One of the effects of a sugar-rich vs a starch-rich meal is highlighted. [1] The blood sugar level, blood sugar concentration, blood glucose level, or glycemia is the measure of glucose concentrated in the blood. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. [2]

  6. Oxidative/fermentation glucose test - Wikipedia

    en.wikipedia.org/.../fermentation_glucose_test

    It was developed in 1953 by Hugh and Leifson to be utilized in microbiology to determine the way a microorganism metabolizes a carbohydrate such as glucose (dextrose). [1] OF-glucose deeps contain glucose as a carbohydrate, peptones, bromothymol blue indicator for Hugh-Leifson's OF medium or phenol red for King's OF medium, and 0.5% agar.

  7. Aerobic fermentation - Wikipedia

    en.wikipedia.org/wiki/Aerobic_fermentation

    The Crabtree effect is a regulatory system whereby respiration is repressed by fermentation, except in low sugar conditions. [1] When Saccharomyces cerevisiae is grown below the sugar threshold and undergoes a respiration metabolism, the fermentation pathway is still fully expressed, [ 9 ] while the respiration pathway is only expressed ...

  8. Lactic acidosis - Wikipedia

    en.wikipedia.org/wiki/Lactic_acidosis

    If there is no oxygen available for the parts of the glucose metabolism that require oxygen (citric acid cycle and oxidative phosphorylation), excess pyruvate will be converted in excess lactate. In "type B" lactic acidosis the lactate accumulates because there is a mismatch between glycolysis activity and the remainder of glucose metabolism.

  9. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. [1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]].
