For short,intense exercise,which energy-producing pathway does the body rely on most?

Question

Quizplus · Accepted Answer

During short, intense exercise, the body relies mostly on anaerobic glycolysis, where glucose is quickly broken down into pyruvate and then converted to lactate in the absence of oxygen. This pathway produces ATP quickly but is not sustainable for prolonged exercise. The other pathways listed take longer to produce ATP or require oxygen, which are not favored during short, intense exercise.
