Aerobic energy systems

ATP - Our energy currency, found in all cells, when released broken down into stored energy

Resynthesise - rebuild/remake

To move our muscles need to contract. to contract we need energy, this is supplied from food, broken down to release chemicals.

Atp

ATP - Immediate usable form of chemical energy

We transfer chemical energy stored in food the energy useful in ATP

Body resynthesises ATP from the breakdown products; ADP + P + Energy = ATP

We don't have a store of ATP so need to make it immediately

3 different types of chemical reactions within the muscle cells; 2 depend of food, 1; dependant on phosphocreatine
