Energy Systems

Question 1

Where is the location of the PC system?

Answer 1

Muscle scaroplasm

Question 2

Is the PC location aerobic/anaerobic?

Answer 2

Anaerobic

Question 3

What is the enzyme used in the PC system?

Answer 3

Creative kinase

Question 4

Are there any fatiguing bi-products in the PC system?

Answer 4

NONE

Question 5

What is the intensity in the PC system?

Answer 5

Maximum

Question 6

What is the duration of the PC system?

Answer 6

3-12 seconds

Question 7

What is the stages of the PC system?

Answer 7

Creatine kinase breaks down phospho-creatine to from creatine, phosphate ion and energy (exothermic). The energy formed then combines with ADP to form 1 ATP (endothermic).

Question 8

What type of reaction is used in the PC system?

Answer 8

A coupled reaction

Question 9

What are the strengths of the PC system?

Answer 9

+ can reform 50% in 30 seconds and full reform in 3 minutes (fast recovery)

+ no fatiguing bi-products

+ a simple reaction with one enzyme

+ a maximum intensity activity

+ no delay for oxygen, instant energy

Question 10

What are the weaknesses of the PC system?

Answer 10

• Only lasts for maximum 12 seconds due to only one ATP and small PC stores
• low ATP yield
