The acronym ATP stands for adenosine triphosphate, which is a chemical; chemicals do not have muscles, the just have atoms.
Muscles need ATP to contract. Mitochondria produce most of the ATP in the cell, so there are lots of mitochondria in muscle.
Muscles are metabolically active. Contractions of muscles cost ATP. So there are many mitochondria
muscle cells produce ATP by cellular respiration through fermentation
The byproduct of ATP when it makes muscles work is ADP and energy. They are not harmful in anyway.
Cellular respiration
tell's them what to do
ATP is used by the body as a source of energy for the muscles.
ATP. And they got ATP from e.g. phosphoenolpyruvate, from glucose.
The reaction that provides energy to power muscles is ATP. ATP loses one phosphate group and converts to ADP.
it is too unstable
Creatine phosphate and ATP are both sources of energy for the muscles. Creatine phosphate is found in vertebrate muscle, while ATP can be found anywhere within the cell.
ATP is important in muscle contraction. ATP is high energy bond which gives you energy required for muscle contraction.
