Energy systems Flashcards
What is ATP
Adenosine Triphosphate
what is ATP the only immediately usable form of
energy stored in the body
what can the ATP compound only be used by
the muscles
where is ATP stored
in muscle cells
how much ATP is available in muscle cells
not a lot, 85g is enough fro 3 seconds
what does ATP consist of one of and how many phosphate groups
one adenosine muscle and 3 phosphate groups
what are the phosphate held together by
chemical bonds
what is the energy in the bond shared between
last 2 phosphate groups
what enzyme breaks down the bond
APhase
what is released when the bond is broken down by the enzyme
energy is released that can be used to make the muscle cell contract and cause movement
what does ATP become once broken down
ADP+P+energy
why do we re-synthesise ATP
the body can only store a very small amount so in order to continue moving we resynthesise it so we can break it down again and keep making energy
what is the equation for resynthesising
ADP+P+energy-ATP
how many different energy systems are there
3
what do the 3 energy systems use differently and do differently
use a different fuel and each one yields a different amount of ATP molecules
