• Cellular respiration

  an exothermic reaction that occurs continuously in the mitochondria of living cells to supply the cells with energy
• Oxygen debt

  the amount of oxygen needed to react with the lactic acid accumulated during anaerobic respiration to remove it from cells
• Aerobic respiration

  complete oxidation of glucose resulting in a large amount of energy being released
• Anaerobic respiration

  incomplete oxidation of glucose leading to much less energy being released per glucose molecule than in aerobic respiration
• Lactic acid

  a substance that builds up in the muscles during anaerobic respiration
• Metabolism

  the sum of all the reactions in a cell or the body, including the synthesis and breakdown of molecules
• Fermentation

  anaerobic respiration in yeast cells, represented by the conversion of glucose to ethanol and carbon dioxide
• Glucose

  a simple sugar that serves as a primary energy source in cellular respiration
• Lipids

  molecules that include fats and oils, synthesized from glycerol and fatty acids
• Proteins

  molecules composed of amino acids, involved in various cellular functions
• Mitochondria

  organelles that contain enzymes for aerobic respiration in cells
• Oxidation


  the process of complete breakdown of glucose to release energy in aerobic respiration
• Carbohydrates

  molecules that include sugars, starch, and cellulose, used as energy sources in respiration
