Description


 ATP Hydrolysis (EC 3.6.1.32):
 [ATP] + [H2O] <-> [ADP] + [Pi] + [H+]
 The hydrolysis of ATP within the cytosol in the presence of ATPase, acts as the primary source
 of ATP degredation in the cell. ATP hydrolysis provides energy for actomyosin contraction.

 Model generated from The Biochemical Simulation Environment (BISEN).
