Answer: read explanation :>

Explanation: During high-energy athletic events like sprints, most of the energy for the muscles comes from glycolysis. This anaerobic pathway breaks down glucose into pyruvate, producing ATP. The Krebs cycle and electron transport chain are aerobic pathways used for lower-intensity activities, while fermentation is a less efficient anaerobic pathway used when oxygen is not available.
