energy, oxygen
carbohydrates, which are broken down into glucose and provide a quick source of energy for the body. However, fat is the most energy-dense macronutrient and provides a longer-lasting source of energy. In the absence of carbohydrates, the body can also use protein as an energy source.
Glycogen
Carbohydrates are the body's preferred energy source because they are easily broken down into glucose, which fuels most of the body's cells and tissues. Proteins and fats can also be used for energy, but carbohydrates are the body's primary and most efficient source of fuel.
yes sugar is an important source of energy because it is considered as a source of endogenous glycation processes.it consists of glucose having the elements Carbon,Hydrogen and Oxygen that are essential for our body
