The process that converts glucose into energy in the presence of oxygen is called aerobic respiration. During this metabolic pathway, glucose undergoes several biochemical reactions, primarily in the mitochondria, where it is broken down to produce adenosine triphosphate (ATP), the energy currency of cells. This process also generates carbon dioxide and water as byproducts. Aerobic respiration is vital for cellular activities, fueling everything from muscle contraction to active transport, thereby supporting overall organismal function and vitality.
