Questions and Answers

How does the ATP yield from an 18-carbon fatty acid compare with the ATP yield from 18 carbons' worth of glucose?

  • ATP yield varies greatly and can't be compared
  • More ATP from fatty acid (correct)
  • Less ATP from fatty acid
  • The same amount of ATP from both

    • Which of the following statements about high-density lipoproteins (HDL) is true?

  • HDL is primarily responsible for transporting triglycerides
  • HDL contributes to the accumulation of fat in tissues
  • HDL carries cholesterol from tissues to the liver (correct)
  • HDL has no role in cholesterol management

    • What is one disadvantage of using fats instead of carbohydrates as energy reserves?

  • Fats require more oxygen for oxidation than carbohydrates (correct)
  • Fats can not store energy as effectively as carbohydrates
  • Fats are less calorically dense than carbohydrates
  • Fats provide energy more quickly than carbohydrates
