HSC PDHPE Core 2: Energy Systems in Sports

What does ATP stand for?

• Adenosine triphosphate

• Adenosine diphosphate

• Anaerobic triphosphate

• Adenosine tetraphosphate

What is the role of ATP in the body's energy systems?

• To serve as the only form of energy the body can use

• To create oxygen

• To store energy

• To produce lactic acid

How does the body replenish ATP from ADP?

• By breaking down creatine phosphate

• By consuming carbohydrates

• Through hydration

• By attaching a phosphate molecule to ADP

Which energy system operates without oxygen?

• Aerobic

• ATP-Phosphocreatine

• Lactic Acid

• Both ATP-Phosphocreatine and Lactic Acid

What is the main source of fuel for the ATP-Phosphocreatine system?

• Protein

• Creatine phosphate

• Fats

• Glycogen

How long does the ATP-Phosphocreatine system last?

• 24 to 48 hours

• 1 to 3 minutes

• 30 seconds to 3 minutes

• 8 to 12 seconds

What is the main source of fuel for the Lactic Acid Energy System?

• Protein

• Fats

• Glycogen

• Creatine phosphate

What causes fatigue in the Lactic Acid Energy System?

• Lack of oxygen

• Shift from glycogen to fats

• Hydrogen ion buildup

• Depletion of creatine phosphate

What is the recovery process for the Lactic Acid Energy System?

• Restoration of creatine phosphate

• Removal of pyruvic acid

• Conversion of ADP to ATP

• Hydration and rest

What is the main byproduct of the Aerobic Energy System?

• Heat

• Water and carbon dioxide

• Phosphate

• Pyruvic acid
