Questions and Answers

What is homeostasis in mammals?

  • The maintenance of unstable internal environment within restricted limits.
  • The maintenance of stable internal environment within restricted limits. (correct)
  • The maintenance of unstable external environment within restricted limits.
  • The maintenance of stable external environment within restricted limits.
  • What are the examples of homeostasis mentioned in the text?

  • Core temperature, blood pH, blood glucose concentration, and blood water potential. (correct)
  • Core temperature, blood pH, blood glucose concentration, and blood pressure
  • Core temperature, blood acidity, blood glucose concentration, and blood water potential.
  • Core temperature, blood alkalinity, blood glucose concentration, and blood water potential.
  • What happens when blood glucose concentration is too high?

  • Enzymes denature and fewer enzyme-substrate complexes are formed
  • ATP production increases and cell death occurs.
  • Dehydration occurs. (correct)
  • Kidneys absorb all glucose causing more water to be lost in urine
  • Study Notes

    1. Homeostasis in mammals is the maintenance of stable internal environment within restricted limits.
    2. Examples of homeostasis include core temperature, blood pH, blood glucose concentration, and blood water potential.
    3. Enzymes have an optimum temperature and pH.
    4. Maintenance of a stable core temperature and blood pH is important for enzyme activity.
    5. Physiological control systems normally involve negative feedback.
    6. Too high or too low blood pH can cause enzymes to denature and fewer enzyme-substrate complexes.
    7. Too low blood glucose concentration can result in less ATP produced and cell death.
    8. Too high blood glucose concentration can cause dehydration.
    9. Water potential of blood decreases when blood glucose concentration is too high.
    10. Kidneys can't absorb all glucose causing more water to be lost in urine.
