About this model
====================
This is a Functional Cell Unit for adenylyl cyclase metabolism in the cardiac cell.
Model status
=============
The current CellML implementation runs in OpenCOR.
Model overview
===================
All components are presented in `bond-graph` form.
Components are made by converting an existing kinetic model and translating into bond-graph form.

Components of the model.
A description of the process to find bond-graph parameter is shown in the folder `parameter_finder <parameter_finder>`_, which relies on:
- stoichiometry of system
- kinetic constants for forward/reverse reactions
- If not already, all reactions are made reversible by assigning a small value to the reverse direction.
- linear algebra script. Here, this solver is performed in Python.
Modular description
===================
Components
----------
CellML divides the mathematical model into distinct components, which are able to be re-used in other composite models.
These CellML components are:
- :math:`{\beta}`-1 adrenergic receptor ( :math:`{\beta}` 1AR)
- Gs Protein
- muscarinic receptor (M2)
- Gi Protein
- cyclic AMP (cAMP)

"`Saucerman et al. <https://models.physiomeproject.org/exposure/9766d9bd0325c31e47a31b291e26ccad>`_", ":math:`{\beta}` 1AR, Gs Protein, cAMP"
"`Iancu et al. <https://models.physiomeproject.org/exposure/f67b68f901fc3986fcea0dcfceb503f9>`_", "M2, Gs Protein"
Each of these blocks is itself a CellML model, which enables us to reuse the various components in future studies.
