  2. Anabolism - Wikipedia

    en.wikipedia.org/wiki/Anabolism

    High amounts of ATP cause cells to favor the anabolic pathway and slow catabolic activity, while excess ADP slows anabolism and favors catabolism. [10] These pathways are also regulated by circadian rhythms , with processes such as glycolysis fluctuating to match an animal's normal periods of activity throughout the day.

  3. Metabolic pathway - Wikipedia

    en.wikipedia.org/wiki/Metabolic_pathway

    The degradative process of a catabolic pathway provides the energy required to conduct the biosynthesis of an anabolic pathway. [6] In addition to the two distinct metabolic pathways is the amphibolic pathway, which can be either catabolic or anabolic based on the need for or the availability of energy.

  4. Energy charge - Wikipedia

    en.wikipedia.org/wiki/Energy_charge

    We now know that most if not all anabolic and catabolic pathways are indeed controlled, directly and indirectly, by the energy charge. [5] [6] [7] In addition to direct regulation of several enzymes by adenyl nucleotides, an AMP-activated protein kinase known as AMP-K phosphorylates and thereby regulates key enzymes when the energy charge ...

  5. Amphibolic - Wikipedia

    en.wikipedia.org/wiki/Amphibolic

    The cell determines whether the amphibolic pathway will function as an anabolic or catabolic pathway by enzyme–mediated regulation at a transcriptional and post-transcriptional level. As many reactions in amphibolic pathways are freely reversible or can be bypassed, irreversible steps that facilitate their dual function are necessary.

  6. Catabolism - Wikipedia

    en.wikipedia.org/wiki/Catabolism

    Endocrinologists have traditionally classified many of the hormones as anabolic or catabolic, depending on which part of metabolism they stimulate. The so-called classic catabolic hormones known since the early 20th century are cortisol, glucagon, and adrenaline (and other catecholamines).

  7. Amino acid synthesis - Wikipedia

    en.wikipedia.org/wiki/Amino_acid_synthesis

    This diagram shows the biosynthesis (anabolism) of amino acids aspartate, asparagine, threonine, methionine, lysine from the precursor oxaloacetate. The associated enzymes are subject to regulation via feedback inhibition and/or repression at the genetic level. As is typical in highly branched metabolic pathways, additional regulation at each ...

  8. Pentose phosphate pathway - Wikipedia

    en.wikipedia.org/wiki/Pentose_phosphate_pathway

    While the pentose phosphate pathway does involve oxidation of glucose, its primary role is anabolic rather than catabolic. The pathway is especially important in red blood cells (erythrocytes). The reactions of the pathway were elucidated in the early 1950s by Bernard Horecker and co-workers. [2] [3] There are two distinct phases in the pathway.

  9. Glyoxylate cycle - Wikipedia

    en.wikipedia.org/wiki/Glyoxylate_cycle

    The seed cannot produce biomass using photosynthesis because of lack of an organ to perform this function. The lipid stores of germinating seeds are used for the formation of the carbohydrates that fuel the growth and development of the organism. The glyoxylate cycle can also provide plants with another aspect of metabolic diversity.
