1
Q

what is phosphate creatin?

A

a high energy compound

2
Q

where is phosphor creatin found?

A

sarcoplasm ( jelly stuff in muscles)

3
Q

what are the three energy systems?

A

atp system
the lactic acid system
the aerobic system

4
Q

what is creatine kinase?

A

the enzyme that breaks down phospho -creatin

5
Q

what enzyme breaks down phospho creatine?

A

creatine kinase

6
Q

how does the brain know when to release the enzyme?

A

when phospho creatin is running low ,and high levels of adp are detected

7
Q

what activates creatine kinase?

A

level of ADP increases

level of ATP decreases

8
Q

where does the energy from used to covert ADP + Pi come from?

A

the break down of phospho creatine

9
Q

what is known as a coupled reaction?

A

when one reaction relies on the occurrence of another to take place

10
Q

how much energy do the stores of pc release?

A

enough energy for all out effort approx. 8- 10 seconds

11
Q

what is an advantage of the PC system?

A

only system that is capable of providing ATP quick enough when performing activities that require high amount of energy

12
Q

what is one way the Pc system is efficient?

A

quick system as pc is simple compound and easy to break down

13
Q

what is a second way the pc system is efficient?

A

it is in muscle cells and is readily available

14
Q

what is the good thing about the pc system?

A

can be obtained quickly from pc and no fatigue by products are released e.g. lactic acid

15
Q

what is the energy of the pc breakdown for?

A

resynthesis ATP

16
Q

what does this process not require?

A

oxygen

17
Q

can we use the energy from the pc to maintain ATP levels?

A

not forever is limited
