Our Energy Production and Its Daily
Our body requires energy for its metabolic and physiological functions. It derives the energy from food and its macronutrient constituents, i.e. carbohydrates, fats, and proteins. The dietary energy intake from food must meet the requirements for the attainment and maintenance of optimal health, physiological function, and well-being. The energy requirement is the amount of food energy needed to maintain body size, body composition, and a level of necessary physical activity consistent with long-term good health. The dietary energy needs cannot be considered in isolation of other nutrients in the diet, as the lack of one will influence the others. Thus, the requirements for energy must be fulfilled through the consumption of a diet that satisfies all nutrient needs. Mitochondria are found in the cytoplasm of all eukaryotic cells, that is, the cells with clearly defined nuclei. Their primary function is to generate large quantities of energy in the form of adenosine triphosphate (ATP)...
