An important role of computational modeling in cell physiology is quantitative hypothesis testing. This role can be seen as having 6 steps:

Overview    Familiarize Yourself With ProcessDB
Step 1    Start With A Diagram of Your Hypothesis
Step 2    Quantify Your Hypothesis
Step 3    Record Your Experimental Protocols
Step 4    Collect Your Experimental Data
Step 5    Run Your Protocols on the Model
Step 6    Test Your Hypothesis Against Your Data
