Chemical reactions can occur when sufficient is supplied to overcome the activation energy. in the lab, heating a mixture of often overcomes the activation energy. an elevation in temperature the kinetic energy of the molecules. this provides enough energy to chemical bonds. this is not feasible in living cells because a change in temperature of this type will cause the proteins to and cause cell . to assist with this problem, cells use biologically active protein catalysts called to facilitate chemical changes.
