L3 - Energy systems recap

Which energy system provides immediate energy for high-intensity, short-duration activities?

• Aerobic system

• Lactate system

• Creatine phosphate system

• Glycolytic system

Which substrates are rarely used in the aerobic energy system?

• ATP and Creatine Phosphate

• Glycogen and glucose

• Proteins

• Fats

What are the primary substrates used in the Lactate and Aerobic systems?

• Fats and proteins

• Creatine phosphate

• Glycogen and glucose

• Water and CO₂

What is the role of lactate in ATP re-synthesis?

• It stores energy for later use

• It breaks down glucose anaerobically to produce ATP

• It provides oxygen for aerobic respiration

• It converts ADP to ATP directly

Which substrate availability affects ATP re-synthesis?

• Water

• Glucose

• Protein

What is a byproduct of anaerobic ATP production?

• Water

• Carbon dioxide

• Lactate

• Oxygen

How long do activities need to last for the aerobic system to predominate?

• 0-10 seconds

• 10-60 seconds

• 60-120 seconds

• Over 2 minutes

Which energy system is associated with the immediate use of ATP and CP?
