PE033_Food Fuels and Energy Systems

Which energy fuel produces the most amount of ATP per molecule?

• triglycerides

• blood glucose

• muscle glycogen

• stored ATP and phosphocreatine

Foods which are high in protein include:

• wholegrain rice, poultry and dairy products.

• soy products, lean meat and fish.

• fish, vegetables and wholegrain rice.

• soy products, fish and avocadoes.

What is the limiting factor of the aerobic energy system?

• Accumulation of hydrogen ions

• Oxygen availability

• Accumulation of carbon dioxide

• PC storage

How much ATP can be stored inside the muscles?

• 1-2 ATP

• 2-3 seconds worth

• 4-5 ATP

• 30 seconds worth

Which of the following is a harmful by product of energy production?

• Lactic acid

• Hydrogen ions

• Carbon dioxide

• ATP

Why does the ATP-PC system provide the most ATP for muscle movement during the high jump?

• It has a very rapid rate of ATP release for the explosive movement

• It causes the least fatigue for the explosive jump

• It has the highest yield of ATP to maximise the explosive power for the jump

• It provides sustained energy throughout the jumping rounds

Which fuel produces the least amount of energy per molecule?

• triglycerides

• blood glucose

• muscle glycogen

• stored ATP and PC

The estimated maximum heart rate of a 50-year-old athlete would be

• 150 bpm

• 170 bpm

• 190 bpm

• 220 bpm

The energy system predominantly used to fuel the 200m sprint (Usain Bolt 19.19 sec) is the:

• Lactic Acid energy system

• Anaerobic glycolysis energy system

• Anaerobic lipolysis energy system

• ATP-PC energy system

• Aerobic lipolysis energy system

Glycogen is stored in which of the following sites in the body?

• Bloodstream

• Liver

• Muscle

• Adipose tissue

• Both B and C
