The ATP-PC system Flashcards
what is phosphate creatin?
a high energy compound
where is phosphor creatin found?
sarcoplasm ( jelly stuff in muscles)
what are the three energy systems?
atp system
the lactic acid system
the aerobic system
what is creatine kinase?
the enzyme that breaks down phospho -creatin
what enzyme breaks down phospho creatine?
creatine kinase
how does the brain know when to release the enzyme?
when phospho creatin is running low ,and high levels of adp are detected
what activates creatine kinase?
level of ADP increases
level of ATP decreases
where does the energy from used to covert ADP + Pi come from?
the break down of phospho creatine
what is known as a coupled reaction?
when one reaction relies on the occurrence of another to take place
how much energy do the stores of pc release?
enough energy for all out effort approx. 8- 10 seconds
what is an advantage of the PC system?
only system that is capable of providing ATP quick enough when performing activities that require high amount of energy
what is one way the Pc system is efficient?
quick system as pc is simple compound and easy to break down
what is a second way the pc system is efficient?
it is in muscle cells and is readily available
what is the good thing about the pc system?
can be obtained quickly from pc and no fatigue by products are released e.g. lactic acid
what is the energy of the pc breakdown for?
resynthesis ATP
