Fermentation & Anaerobic Respiration definitions
1/15
  • Fermentation

    A process that regenerates NAD+ from NADH, allowing glycolysis to continue in the absence of oxygen.
  • Anaerobic Respiration

    Respiration using alternative electron acceptors instead of oxygen, producing more ATP than fermentation.
  • NAD+

    An electron carrier that is regenerated during fermentation, enabling glycolysis to continue.
  • NADH

    An electron carrier that accumulates when oxygen is absent, leading to fermentation.
  • Glycolysis

    The first step of cellular respiration that continues in the absence of oxygen due to fermentation.
  • Lactic Acid

    A product of lactic acid fermentation, formed by reducing pyruvate, regenerating NAD+.
  • Ethanol

    A type of alcohol produced during alcohol fermentation by reducing pyruvate.
  • Electron Transport Chain

    A series of complexes that transfer electrons, requiring a final electron acceptor like oxygen.
  • Pyruvate

    A key intermediate in metabolism, reduced to lactic acid or ethanol during fermentation.
  • Krebs Cycle

    A stage in aerobic respiration that does not occur without oxygen.
  • Chemiosmosis

    A process in aerobic respiration for ATP production, halted without oxygen.
  • Nitrate

    An alternative electron acceptor used in anaerobic respiration.
  • Sulfate

    Another alternative electron acceptor used in anaerobic respiration.
  • Oxidative Phosphorylation

    ATP production process in aerobic respiration, requiring oxygen as the final electron acceptor.
  • ATP

    The energy currency of the cell, produced in small amounts during fermentation.
