It depends on the type of carbohydrate. Simple carbohydrates (or sugars), such as glucose and fructose, are absorbed into the bloodstream and provide an immediate energy boost, and are the most quickly turned into energy. Other carbohydrates, such as starch, take more time to digest and are probably similar energy wise as protein or fats. However, as far as containing the most energy in a given amount, fats beat all carbohydrates and proteins by far.
When your body runs out of carbohydrate energy, it gets more energy from breaking down stored fat or protein.
If you mean why: because it is a much more efficient way to store energy than, say, a carbohydrate. You would need twice the amount of carbohydrate molecules to give the same amount of energy.
The Polysaccharides
Carbohydrates are stored as complex sugars. The larger molecules are called starch and bigger than that is cellulose.
adipose tissue
they contain more energy than a carbohydrate
"Stored energy" sounds more like potential energy. Kinetic energy is the energy related to movement.
Glycogen is a form of carbohydrate which is stored in the liver for short term energy needs, after which the body will begin breaking down fats (lipids) for energy. The answer is Complex Carbs
Polysaccharides contain more glucose units, which means more potential energy can be stored in the form of chemical bonds. This structure allows polysaccharides to be broken down gradually, providing a sustained source of energy for the body. Monosaccharides, on the other hand, supply quick but short-lived bursts of energy due to their simple structure.
Chemical energy is stored in batteries, food, and other molecules. When these substances undergo chemical reactions, the stored energy is released.
glycogen is a more complex carbohydrate than glucose. macromolecules are stored as complex molecules for example lipids are stored as complex fat.
More energy is stored in ATP (adenosine triphosphate) compared to ADP (adenosine diphosphate), due to the presence of three phosphate groups in ATP compared to two in ADP. The third phosphate group in ATP represents high-energy bonds that can be readily broken to release energy for cellular processes.
