Answer: Adenosine triphosphate
What fuel source is primarily broken down during anaerobic glycolysis?
Answer: Glucose/glycogen
What is the main characteristic of the aerobic energy system?v
Answer: It requires oxygen to produce ATP
Which energy system is dominant during a 10-second maximal sprint?
Answer: ATP-PC
Approximately how long can the ATP-PC system provide energy at maximal intensity?
Answer: 10 seconds
What is a major by-product associated with anaerobic glycolysis?
Answer: Lactate
What does the aerobic energy system require to produce ATP?
Answer: Oxygen.
Which energy system is most important during a 5 km run?
Answer: Aerobic
What stored substance is broken down to rapidly resynthesise ATP in the ATP-PC system?
Answer: Phosphocreatine (PC)
Why can anaerobic glycolysis produce ATP quickly?
Answer: It breaks down glucose rapidly without requiring oxygen

Answer: Carbohydrates and fats
A basketball player performs repeated high-intensity efforts with short recovery periods. Which two systems are likely to contribute significantly?
Answer: ATP-PC and anaerobic glycolysis
Explain why the ATP-PC system is suited to explosive movements such as jumping.
Answer: It provides ATP rapidly without oxygen
What is one advantage of anaerobic glycolysis?
Answer: It can provide energy quickly without oxygen.
Why can the aerobic system provide energy for a long time?
Answer: It uses oxygen to continually produce ATP.
A soccer player sprints for 5 seconds to chase the ball. Which energy system is mainly used?
Answer: ATP-PC
Give one sporting example where the ATP-PC system is mainly used.
Answer: Shot put, long jump, 100 m sprint, or weightlifting.
Give one sporting example where anaerobic glycolysis is important.
Answer: 400 m sprint, 800 m run, or repeated high-intensity efforts.
Give one sporting example where the aerobic system is mainly used.
Answer: Marathon, long-distance running, or cycling.
A marathon runner and a 100 m sprinter use different energy systems. Which system is most important for each?
Answer: Marathon = aerobic; 100 m sprint = ATP-PC.
