This is power stored in ~ chemical bond of #ATP# #("Energy currency")#. #"ATP"# is one abrupt source of chemical power stored in ~ glucose molecules in muscle tissues.

You are watching: Where in a molecule is energy stored

The energy stored in the bond that organized the atoms of molecule together is dubbed chemical energy.

And #"ATP"# is one immediate source of chemical energy for muscle contraction. #"ATP"# molecule is capable to store and also transport chemical energy within muscle cells. In ATP , 3 phosphate molecule are linked by high-energy bonds.


When #"ATP"# is hydrolyzed climate these bonds break thus power is released. The energy released helps myosin and actin filaments come overlap and start contraction.


Hope it helps...

Energy currency of every living cell is ATP (adenosine triphosphate) but this have the right to not it is in stored in huge amount.

ATP molecule are produced by moving respiration: this molecule releases power by breaking right into ADP and inorganic phosphate, the reaction is catalysed by ATPase enzyme.


ATP save on computer in muscles may last just 10 seconds of exercise. additionally consider the reality that ATP is a heavy molecule: molar mass of ATP is an ext than 500g/mol. Storage of ATP would have abnormally increased our weight. So it is organic that ATP is not stored in huge amount however is repetitively generated.

In muscle tissues, a distinct molecule called phosphocreatine is stored which can adjust an ADP automatically in an ATP in presence of enzyme.

About 120 gram the phosphocreatine is save on computer in our muscles.


To generate ATP, ours muscle cells can use glucose together raw product for cellular respiration. About 500 gram that glycogen is save on computer in skeletal muscle of an adult body. The glycogen readily provides glucose for manufacturing of ATP (both aerobically and also anaerobically).


Skeletal muscles store an additional molecule named myoglobin i m sorry can quickly supply oxygen for aerobic respiration when there is a decline in concentration of oxygen in muscle.

Myoglobin has a higher affinity in the direction of oxygen, for this reason it dissociates native oxygen just at a lower partial push of oxygen compared to haemoglobin.
