Question

Triglycerides contain more metabolic energy per unit weight than glycogen because:

Answer 1

Answer:

Triglycerides contain more metabolic energy per unit weight than glycogen because  it is water-insoluble. Triglycerides (fats and oils) are important dietary  sources of energy and they can be stored in  larger quantities than carbohydrates.  Fat also functions as a major  form of energy storage (9 Cal/g).

Carbohydrate reserves are depleted after about 1  day without food, but stored fat can provide needed calories for 30-40 days

Explanation:

Carbohydrates from dietary sources and glycogen  catabolism are used preferentially for energy  production by some tissues, such as the brain and active skeletal muscles.

Body stores of glycogen are depleted after only a

few hours of fasting, which requires fatty acids

stored in triglycerides to be used as energy sources.

Even if glycogen supplies are adequate,  resting muscle and liver cells use energy from  triglycerides because this conserves glycogen  stores and glucose for use by brain cells and red  blood cells.

Answer 2

Triglycerides  contain  more  metabolic  energy   per   unit  weight  glycogen   because
1  Glycogen  has     polarity  is  more than  that  of fatty  acids
2.  fatty  acids  are  commonly  in  anhydrous  form
3.fatty  acid  are   less  oxidized   than  the   carbohydrate
   Triglyceride  contain  double    energy  to  that  of  carbohydrate  or  that  of  energy that  can   be  supplied  in   the   body.
