The Equivalence Of ATP In Calories
As humans, like every organism that exists, we need sustenance in the form of nutrients to survive. Humans derive these important nutrients from substances they call food. Food eaten by humans is either obtained from a plant or an animal source. Whatever the source is, the food ingested by a man contains a specific nutrient that performs different functions in his body. The various effects of these nutrients are largely used to classify foods into different groups.
Proteinous food contains a high percentage of proteins in its nutrient makeup. Their main function is to serve as bodybuilding food, it provides materials which can be used by your body to repair or replace odd tissues. Carbohydrate-rich food is the main source of energy for your bodily functions, while fats serve as an alternative source of energy that can be utilized instead of carbohydrates. Vitamins/minerals contribute to important processes in the body and help maintain the general health of the body.
A major function of food is to serve as a source of energy, but not all the foods you take in can supply you energy or enough energy needed by your body. Foods high in carbs and fats provide a massive amount of energy to your body. Proteins which are high-valued nutrients in your body due to their vital functions in the body can also be used to derive energy. However, the body only uses protein as a last resort, when there is little or no supply of carbs and fats in your body. During digestion energy-producing nutrients are broken down to give energy in the form of Adenosine triphosphate.
The energy derived from nutrient is stored inside the P-P bond of ATP. This energy containing molecule serves as the energy currency of the body, and it is used to carry out different activities at the cellular level of an organism. A single molecule of ATP has 7.3 kilocalories stored within its bonds, which can be accessed by your body through the dephosphorylation of these bonds.
