Understanding Energy Systems in the Human Body

What is the primary compound used by muscles for immediate energy?

• Glucose

• Lactate

• Glycogen

• ATP

Which energy system is utilized for quick, powerful movements like a golf swing?

• Oxidative system

• Glycolytic system

• ATP PCR system

• None of the above

For how long can the ATP PCR system provide energy for movement?

• Up to 15 seconds

• Up to 1 minute

• Up to 2 minutes

• Indefinitely

What byproduct is formed during the glycolytic system that contributes to muscle fatigue?

• Oxygen

• Lactate

• Creatine phosphate

• ATP

What is the main source of energy for the glycolytic system?

• Glucose and glycogen

• ATP

• Fats

• Proteins

What effect does lactate have on muscles during high-intensity exercise?

• Decreases pH and causes fatigue

• Increases energy production

• Increases oxygen availability

• Has no effect

Which energy system can use fats, proteins, and carbohydrates to produce ATP?

• Glycolytic system

• All of the above

• ATP PCR system

• Oxidative system

Which metabolic processes are involved in the oxidative system?

• None of the above

• Electron transport chain and Glycolysis

• Krebs cycle and Electron transport chain

• Glycolysis and Krebs cycle

How can one improve the efficiency of the ATP PCR system?

• High-intensity interval training

• Explosive movements like box jumps

• Long-distance running

• Low-intensity steady-state cardio

Which type of exercise would primarily improve the oxidative system?

• Jumping rope

• Long-distance running

• Weightlifting

• Sprinting
