A diet rich in micronutrients is crucial because vitamins and minerals act as cofactors necessary for the enzymatic reactions that release energy. These organelles act as microscopic power plants, converting biochemical energy from nutrients into adenosine triphosphate (ATP).

Macronutrient Calories per Gram Primary Role Carbohydrate 4 Quick energy for brain and muscles Fat 9 Long-term energy storage and cell structure Protein 4 Tissue repair and enzyme production Mitochondria: The Cellular Power Plants Regardless of the initial fuel source, the final stage of energy production occurs within the trillions of mitochondria found in human cells. Once ingested, complex starches and simple sugars are digested and enter the bloodstream, prompting a rise in blood sugar.
ATP is the universal energy currency that powers everything from cellular repair to neural transmission. These molecules are essential for hormone production and nutrient absorption.
