During prolonged fasting, fatty-acid breakdown supplies acetyl-CoA to the liver. Which outcome can help provide fuel to other tissues?

  1. A

    The liver stores the acetyl-CoA as muscle glycogen.

A cell breaks down nutrient molecules and captures some of the released energy in ATP. Which process best describes this activity?

  1. A

    Anabolism, because it builds compounds using energy

  2. B

    Catabolism, because it breaks down nutrients and releases usable energy

  3. C

    Glycogenesis, because it stores glucose as glycogen

  4. D

    Gluconeogenesis, because it makes glucose from non-carbohydrate precursors

After a carbohydrate-containing meal, which response is most consistent with the usual effects of insulin?

  1. A

    It promotes the release of stored fuels and reduces nutrient uptake

  2. B

    It directly converts all absorbed glucose into ketone bodies

  3. C

    It generally favors nutrient uptake and storage while reducing release of stored fuels

  4. D

    It prevents glycogen and fat synthesis until fasting begins
