Before revision:  In the present study,  a mathematical model describing the reaction kinetics of the two apoptosis-inducing signaling pathways is developed and used to theoretically investigate their catalase-dependent reactivation. The results show that when only the reaction kinetics is considered, just one of the pathways may be responsible for apoptosis induction.
