The ATP-PCr system

Question 1

At what intensity is this energy system used?

Answer 1

Used in shorts bursts of very high intensity

Question 2

How is ATP produced within this system?

Answer 2

Does not require oxygen
Readily available in the cell
ADP - free phosphate group is added to make it ATP

Question 3

What are some activities that would use the ATP-PCr system?

Answer 3

Penalty stroke
Shot putt throw
Hit over the net in volleyball
Header in football

Question 4

What is one limitation of this system?

Answer 4

Stores are depleted within 10 seconds so can only be used for very short periods of time

Question 5

How long does it take for the phosphocreatine system to be replenished?

Answer 5

3-5 minutes for a full recovery

Question 6

What does PCr stand for?

Answer 6

Phosphocreatine system

Question 7

What are 2 benefits of the ATP-PCr system?

Answer 7

The reaction does not require oxygen (anaerobic)

It does not produce lactic acid as a bi-product (alactic)

Question 8

Where is the phosphocreatine produced?

Answer 8

In the muscle cells

Question 9

What is ATP?

Answer 9

Adenosine triphosphate

Question 10

What is ADP?

Answer 10

Adenosine diphosphate

Question 11

How is adenosine diphosphate produced?

Answer 11

Adenosine triphosphate is when one phosphate group bond is broken and ADP is now produced because there is only 2 phosphate groups present
