Table 1 Birth and death reactions for the hybrid model

R₁ : T ↦ T + 1

a₁ = r₂T

R₂ : T ↦ T - 1

$a_2=\frac{r_{2}b}{V}{T}^2$

R₃ : T ↦ T - 1

$a_3=\frac{p_{T}TE}{g_{T}V+T}$

R₄ : E ↦ E + 1

$a_4\left(t\right)=\frac{p_{E}EI\left(t\right)}{g_E+I\left(t\right)}$

R₅ : E ↦ E - 1

a₅ = μ _E E

R₆ : E ↦ E + 1

a₆ = cT

R₇ : E ↦ E + 1

a₇ = Vσ _E
