  2. 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 ]].

  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. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    The metabolic pathway in the cell is regulated by covalent or non-covalent modifications. A covalent modification involves an addition or removal of a chemical bond, whereas a non-covalent modification (also known as allosteric regulation) is the binding of the regulator to the enzyme via hydrogen bonds , electrostatic interactions, and Van der ...

  5. Carbohydrate catabolism - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate_catabolism

    Glycolysis, which means “sugar splitting,” is the initial process in the cellular respiration pathway. Glycolysis can be either an aerobic or anaerobic process. When oxygen is present, glycolysis continues along the aerobic respiration pathway. If oxygen is not present, then ATP production is restricted to anaerobic respiration.

  6. Redox - Wikipedia

    en.wikipedia.org/wiki/Redox

    Cellular respiration, for instance, is the oxidation of glucose (C 6 H 12 O 6) to CO 2 and the reduction of oxygen to water. The summary equation for cellular respiration is: C 6 H 12 O 6 + 6 O 2 → 6 CO 2 + 6 H 2 O + Energy. The process of cellular respiration also depends heavily on the reduction of NAD + to NADH and the reverse reaction ...

    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 ...

  9. Pyruvate dehydrogenase complex - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_dehydrogenase_complex

    Acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration, and this complex links the glycolysis metabolic pathway to the citric acid cycle. Pyruvate decarboxylation is also known as the "pyruvate dehydrogenase reaction" because it also involves the oxidation of pyruvate. [2]
