Quizplus · Accepted Answer

Running a marathon requires sustained energy production, which is primarily supplied by aerobic glucose breakdown (also known as cellular respiration). While some ATP may be produced from the breakdown of amino acids or fatty acids, these processes are not efficient enough to sustain the energy demands of a marathon. Anaerobic glucose breakdown (glycolysis) can provide energy quickly, but it is not sustainable for the duration of a marathon and can lead to the production of lactic acid, causing fatigue and muscle soreness.
