  2. Aerobic fermentation - Wikipedia

    en.wikipedia.org/wiki/Aerobic_fermentation

    Aerobic fermentation or aerobic glycolysis is a metabolic process by which ... ATP and regenerate NAD + to allow for glycolysis to continue. For most plant tissues ...

  3. 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 ...

  4. Cellular respiration - Wikipedia

    en.wikipedia.org/wiki/Cellular_respiration

    Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]]. [2] [better source needed] Respiration can be either aerobic, requiring oxygen, or anaerobic; some organisms can switch between aerobic and anaerobic respiration. [3] [better source needed]

  5. Carbohydrate metabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_metabolism

    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] During the first phase, it requires the breakdown of two ATP molecules. [1]

  6. Bioenergetic systems - Wikipedia

    en.wikipedia.org/wiki/Bioenergetic_systems

    Glycolysis takes place in the cytoplasm of normal body cells, or the sarcoplasm of muscle cells. The Krebs cycle – This is the second stage, and the products of this stage of the aerobic system are a net production of one ATP, one carbon dioxide molecule, three reduced NAD + molecules, and one reduced flavin adenine dinucleotide (FAD

  7. Pasteur effect - Wikipedia

    en.wikipedia.org/wiki/Pasteur_effect

    The increased ATP and citrate from aerobic respiration allosterically inhibit the glycolysis enzyme phosphofructokinase 1 because less pyruvate is needed to produce the same amount of ATP. Despite this energetic incentive, Rosario Lagunas has shown that yeast continue to partially ferment available glucose into ethanol for many reasons. [ 1 ]

  8. Gluconeogenesis - Wikipedia

    en.wikipedia.org/wiki/Gluconeogenesis

    It is proposed that fructose 1,6-bisphosphate aldolase/phosphatase was an ancestral gluconeogenic enzyme and had preceded glycolysis. [37] However, a prebiotic glycolysis would follow the same chemical mechanisms as gluconeogenesis, due to microscopic reversibility, and in this view would have occurred at the same time.

  9. Metabolism - Wikipedia

    en.wikipedia.org/wiki/Metabolism

    Metabolism (/ m ə ˈ t æ b ə l ɪ z ə m /, from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical reactions in organisms.The three main functions of metabolism are: the conversion of the energy in food to energy available to run cellular processes; the conversion of food to building blocks of proteins, lipids, nucleic acids, and some carbohydrates; and the ...
