Introduction to Metabolism definitions
1/10
  • Metabolism

    Refers to all chemical reactions within an organism, encompassing both catabolic and anabolic pathways.
  • Metabolic Pathways

    Series of enzyme-mediated steps that transform substrates into final products through multiple intermediates.
  • Substrate

    Initial molecule in a metabolic pathway that undergoes transformation through enzyme-catalyzed reactions.
  • Enzyme

    Protein that catalyzes chemical reactions, facilitating the conversion of substrates in metabolic pathways.
  • Catabolic Pathways

    Processes that break down molecules into smaller units, releasing energy, and are linked to exergonic reactions.
  • Anabolic Pathways

    Processes that synthesize larger molecules from smaller ones, requiring energy input, and are linked to endergonic reactions.
  • Exergonic Processes

    Reactions that release energy into the environment, often associated with catabolic pathways.
  • Endergonic Processes

    Reactions that require energy input, often associated with anabolic pathways.
  • Final Product

    The end molecule produced in a metabolic pathway after all enzymatic transformations.
  • Intermediate

    Molecule formed between the initial substrate and final product in a metabolic pathway.
