What are the disadvantages of aerobic system?

The aerobic system, while efficient for prolonged energy production, has several disadvantages. It requires oxygen, making it less effective during high-intensity activities where oxygen supply may be limited. Additionally, the process is slower in generating ATP compared to anaerobic systems, which can be a drawback in situations that demand rapid bursts of energy. Lastly, prolonged reliance on the aerobic system can lead to fatigue due to the accumulation of metabolic byproducts like carbon dioxide.
