During prolonged, intense exercise, human muscles primarily rely on lactic acid fermentation to supply energy. This anaerobic pathway allows for the rapid production of ATP when oxygen levels are low, such as during intense physical activity. While the citric acid cycle and electron transport chain are involved in aerobic respiration, they require oxygen and are not efficient during intense exercise when oxygen is limited. Alcoholic fermentation is not a pathway utilized by human muscle cells.
