L3 Anatomy and Physiology - Energy Systems

Which energy system provides our immediate energy?

• ATP-PC
• Lactic Acid
• Aerobic

Why might the lactic acid system be used for sprinting after 70 minutes?

• Because you have not got enough time to fully replenish PC stores.
• You become lazy and therefore don't use the PC system.
• Because you are so tired you can no longer sprint. 
• You are now working at a lower intensity than you was previously. 

Cross country skiing could be an example to use which energy system?

• ATP-PC

• Lactic Acid

• Aerobic/oxidative

• None of the above

What is the fuel for ATP-PC

• glucose
• phosphocreatine
• fatty acids
• fats

Which energy system will be used for the shortest bout of exercise?

• ATP-PC

• Lactic Acid

• Aerobic

• None of the above

ATP consists of the following:-

• Adrenaline, 2 phosphate molecules

• Adenosine, 2 phosphate molecules

• Adenosine, 3 phosphate molecules

• Adenosine, 4 phosphate molecules

A 50 metre sprint would use which energy system?

• Aerobic

• ATP-PC

• Lactic Acid

• None of the above

A marathon would use which of the energy systems?

• Aerobic

• ATP-PC

• Lactic Acid

• None of the above

The body's main source of energy

• Protein

• Vitamins

• minerals

• Carbohydrates

What are the three sources of calories?

• Carbohydrates, Proteins, and Sugars

• Proteins, Starches, and Sugars

• Fat, Proteins, and Amino Acids

• Carbohydrates, Proteins, and Fats
