Anaerobic Energy Systems: ATP-PC System & Glycolytic System

What does PC stand for in the ATP-PC system?

• Glycogen

• Phosphokinase

• Phosphocreatine

• Phosphocreator

Phosphocreatine is an energy-rich phosphate compound found in the (a)   of the muscle cells.

Which types of movement does the ATP-PC system provide energy for?

• 200m Sprint

  200m Swim

• Shot put

  Long jump take off

  Tennis serve

• Marathon

  Tour de France

• Cross country skiing

  Dancing

A disadvantage of the ATP-PC system is that stores of PC are limited and only last for up to 10 seconds, and can only be replenished when (a)   is present.

1 molecule of phosphocreatine produces how many molecules of ATP?

(a)  

The ATP-PC system can provide energy to resynthesise ADP to ATP, known as a (a)   reaction.

Does the ATP-PC system produce fatiguing by-products?

• Yes

• No

How long does it take to replenish stores of phosphocreatine?

• 1 min = 75%

  4 mins = 90%

• 1 min = 50%

  4 mins = 100%

• 30s = 75%

  3 mins = 90%

• 30s = 50%

  3 mins = 100%

Creatine supplementation can be used to (a)   the time the ATP-PC system can be utilised.

Which enzyme is used to break down ATP into ADP? Responsible for splitting off the third molecule of phosphate to produce energy?

• ATPase

• ATPi

• Phosphofructokinase

• creatine kinase
