Detailed explanation-1: -The most important monosaccharide is glucose, a carbohydrate with the molecular formula C6H12O6. Glucose is the basic form of fuel in living things. In multicellular organisms, it is soluble and is transported by body fluids to all cells, where it is metabolized to release its energy.

Detailed explanation-2: -ATP is an organic compound that is the main source of energy for all living systems. Certain researchers prefer to call glucose the main source of energy, but glucose is catabolized into energy. Basically, there are four sources of energy: carbohydrates, lipids, proteins and nucleic acids.

Detailed explanation-3: -Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

Detailed explanation-4: -Answer and Explanation: The organic compound that stores the most energy is lipids. Lipids are fats and one of their main jobs in the body is to store energy. In fact, lipids can be used to generate about twice as much energy as carbohydrates.
