Questions and Answers

What are the four main categories of energy lost as heat?

  • Standard metabolism, Voluntary physical activity, Heat of nutrient metabolism, Specific dynamic action
  • Standard metabolism, Voluntary physical activity, Heat of nutrient metabolism, Production energy
  • Basal metabolism, Voluntary physical activity, Heat of nutrient metabolism, Specific dynamic action (correct)
  • Basal metabolism, Voluntary physical activity, Heat of nutrient metabolism, Production energy
  • Basal metabolism is the energy required to keep the animal alive, and is similar to basal metabolism measured in humans.

    True

    Production energy is a part of maintenance energy.

    False

    Specific dynamic action is the heat released by the many chemical reactions associated with the processing of ingested feed.

    Study Notes

    Fish Immunity

    • Fish have an immune system
    • Fish are cold-blooded animals

    Digestion and Metabolism

    • Catabolic reactions transfer energy from complex molecules to ATP
    • Anabolic reactions transfer energy from ATP to complex molecules
    • Simple molecules such as glucose, amino acids, glycerol, and fatty acids
    • Complex molecules such as starch, protein, and lipids
    • Food molecules: sugar, lipids, proteins (high-enthalpy, low-entropy compounds)
    • CO2, waste products (low-enthalpy, high-entropy compounds)
    • Cell components: membranes, proteins, nucleic acids (high-enthalpy, low-entropy compounds)
    • Simple precursors (low-enthalpy, high-entropy compounds)

    Feed Manufacturing Stages

    • Not covered in this text.
