# Model Mathematics, Interactive Component Viewer

When the graph appears, select a component to see its associated
mathematical equations. Elements within the viewport can be rearranged
by click and drag with the cursor. The viewport can be moved by click
and drag on an empty area. Zooming can be adjusted by the scroll wheel.

### Component: IP3

$\u2202\u2202 time P = D_P \u2062 Pxx + Pyy $

### Component: calcium

$\u2202\u2202 time c = D_c \u2062 cxx + cyy + J_channel + J_leak +- J_pump $

### Component: IP3_receptor

$ J_channel = k_flux \u2062 mu_P \u2062 h \u2062 b + 1.0 - b \u2062 c k1 + c mu_P = mu_0 + mu_1 \u2062 P k_mu + P $

### Component: IP3_receptor_h_gate

$dd time h = h_infinity - h tau_h h_infinity = k2 2.0 k2 2.0 + c 2.0 $

### Component: calcium_pump

$ J_pump = gamma \u2062 c k_gamma + c $

### Component: calcium_leak

$ J_leak = beta $
