  2. Glycolysis - Wikipedia

    en.wikipedia.org/wiki/Glycolysis

    d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...

  3. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    Glucose regulation and product use are the primary categories in which these pathways differ between organisms. [2] In some tissues and organisms, glycolysis is the sole method of energy production. [2] This pathway is common to both anaerobic and aerobic respiration. [1] Glycolysis consists of ten steps, split into two phases. [2]

  4. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    Glycolysis results in the breakdown of glucose, but several reactions in the glycolysis pathway are reversible and participate in the re-synthesis of glucose (gluconeogenesis). [9] Glycolysis was the first metabolic pathway discovered: As glucose enters a cell, it is immediately phosphorylated by ATP to glucose 6-phosphate in the irreversible ...

  5. Carbohydrate catabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_catabolism

    Glucose reacts with oxygen in the following reaction, C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O. Carbon dioxide and water are waste products, and the overall reaction is exothermic. The reaction of glucose with oxygen releasing energy in the form of molecules of ATP is therefore one of the most important biochemical pathways found in living organisms.

  6. Blood sugar regulation - Wikipedia

    en.wikipedia.org/wiki/Blood_sugar_regulation

    Ball-and-stick model of a glucose molecule. Blood sugar regulation is the process by which the levels of blood sugar, the common name for glucose dissolved in blood plasma, are maintained by the body within a narrow range. The regulation of glucose levels through Homeostasis. This tight regulation is referred to as glucose homeostasis.

  7. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Starting with glucose, 1 ATP is used to donate a phosphate to glucose to produce glucose 6-phosphate. Glycogen can be converted into glucose 6-phosphate as well with the help of glycogen phosphorylase. During energy metabolism, glucose 6-phosphate becomes fructose 6-phosphate.

  8. Cori cycle - Wikipedia

    en.wikipedia.org/wiki/Cori_cycle

    Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.

  9. Gluconeogenesis - Wikipedia

    en.wikipedia.org/wiki/Gluconeogenesis

    The final step in gluconeogenesis, the formation of glucose, occurs in the lumen of the endoplasmic reticulum, where glucose-6-phosphate is hydrolyzed by glucose-6-phosphatase to produce glucose and release an inorganic phosphate. Like two steps prior, this step is not a simple reversal of glycolysis, in which hexokinase catalyzes the ...
