• adenosine triphosphate (ATP)

• carbohydrates

• Fats & protein

Select the two ways our muscles can produce energy

• Creatine production (using oxygen)

• Anaerobic energy production (not using oxygen)

• Lactic acid production

• Aerobic energy production (using oxygen)

What are the two anaerobic systems?
