Energy Pathways

Meaning

Energy pathways refer to the complex biochemical routes within cells that convert macronutrients—carbohydrates, fats, and proteins—into adenosine triphosphate (ATP), the primary energy currency of the body. These metabolic sequences facilitate the controlled release of chemical energy from nutrient substrates, enabling vital cellular functions such as muscle contraction, nerve impulse transmission, and hormone synthesis. Efficient operation of these pathways is fundamental for sustaining physiological processes and maintaining cellular integrity across all tissues.
