Energy Systems revision

What is ATP?

• A chemical compound containing one adenosine and three phosphate molecules

• A type of carbohydrate found in meat and fish

• A by-product of anaerobic glycolysis

• A fuel source used during rest and low intensities

What happens when ATP breaks down?

• One high energy bond breaks and one phosphate molecule is released

• One phosphate molecule breaks and one high energy bond is released

• Two high energy bonds break and two phosphate molecules are released

• Two phosphate molecules break and two high energy bonds are released

Which fuel source is used during short bursts of high intensity activity?

• Creatine Phosphate

• Carbohydrates

• Fats

• Protein

What is the Glycaemic Index (GI) used for?

• Ranking carbohydrate foods based on how rapidly glucose is released into the blood stream

• Determining the amount of ATP needed for an activity

• Measuring the rate of ATP resynthesis

• Calculating the yield of ATP from different fuel sources

Which energy system is the fastest rate of ATP resynthesis?

• ATP-PC system

• Anaerobic glycolysis

• Aerobic glycolysis

• Aerobic lipolysis

What is the predominant energy system during a marathon?

• ATP-PC system

• Anaerobic glycolysis

• Aerobic glycolysis

• Aerobic lipolysis

What is the by-product of anaerobic glycolysis that causes fatigue?

• Lactic acid

• Creatine phosphate

• Glycogen

• Triglycerides

Which energy system requires oxygen?

• ATP-PC system

• Anaerobic glycolysis

• Aerobic glycolysis

• Aerobic lipolysis

What is the predominant energy system during low intensity exercise?

• ATP-PC system

• Anaerobic glycolysis

• Aerobic glycolysis

• Aerobic lipolysis

What is the cause of fatigue in the anaerobic glycolysis system?

• Depletion of fuel stores

• Accumulation of metabolic by-products

• Lack of oxygen

• Inadequate ATP resynthesis
