Schematic diagram showing anabolism and catabolism. Anabolism (/ ə ˈ n æ b ə l ɪ z ə m /) is the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units. [1] [2] These reactions require energy, known also as an endergonic process. [3] Anabolism is the building-up aspect of metabolism, whereas catabolism is
Degradation of nucleic acids is a catabolic reaction and the resulting parts of the nucleotides or nucleobases can be salvaged to recreate new nucleotides. Both synthesis and degradation reactions require multiple enzymes to facilitate the event. Defects or deficiencies in these enzymes can lead to a variety of diseases. [1]
The process of bind an amino acid to a tRNA is known as tRNA charging. Here, the enzyme aminoacyl-tRNA-synthetase catalyzes two reactions. In the first one, it attaches an AMP molecule (cleaved from ATP) to the amino acid. The second reaction cleaves the aminoacyl-AMP producing the energy to join the amino acid to the tRNA molecule. [14]
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 ...

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.
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.
