ATP-PC system

Question 1

Describe the ATP-PC system

Answer 1

1. Anaerobic reaction
2. Phosphocreatine is the fuel used
3. Sarcoplasm
4. Creatine kinase
5. 1 mole of ATP are produced
6. Very high intensity
7. 2-10 seconds

Question 2

What are the specific stages of the ATP-PC system?

Answer 2

1. PC is broken down by creatine kinase to release energy.

2. The same pocket of energy then builds up ADP+P to form ATP.

Question 3

What is the equation for the ATP-PC system?

Answer 3

1. PC –> P + C + energy

2. energy + ADP + P –> ATP

Question 4

What are the advantages of the ATP-PC system?

Answer 4

1. Simple and rapid breakdown
2. Provides energy quickly
3. No fatiguing by-products
4. No delay for oxygen

Question 5

What are the disadvantages of the ATP-PC system?

Answer 5

Low ATP yield and small PC stores lead to rapid fatigue after 8-10 seconds.

Question 6

What is a coupled reaction?

Answer 6

A coupled reaction is where products of one reaction are used in another reaction
