Which energy system has the highest capacity for ATP production?

Fatty acid oxidation system
Aerobic (glycolytic) system
Anaerobic (glycolytic) system
ATP-CP (phosphagen) system

The correct answer is: Fatty acid oxidation system

Fatty acid oxidation system has the highest capacity for ATP production because it uses the energy from breaking down fats to generate ATP, which results in a large amount of ATP being produced. The other energy systems do not have as much energy available to produce ATP compared to the fatty acid oxidation system. Aerobic (glycolytic) system uses glucose and oxygen to produce ATP, but it is not as efficient as breaking down fats in terms of ATP production. Anaerobic (glycolytic) system can produce ATP quickly but in small amounts and the ATP-CP (phosphagen) system has the smallest capacity for ATP production, as it only has a limited amount of creatine phosphate available for ATP production. This makes the fatty acid oxidation system the most efficient and long-lasting energy system for ATP production.
