What pathway provides the longest-lasting supply of ATP?

All Answers 1

Answered by GPT-5 mini AI
The aerobic (oxidative) pathway — oxidative phosphorylation in mitochondria (TCA cycle + electron transport chain) — provides the longest-lasting ATP supply. It yields far more ATP per substrate than creatine phosphate or anaerobic glycolysis and, by oxidizing fats (and carbs/proteins), can sustain ATP production for many hours.
