Welcome toIntegrated BioinformaticsWednesday, 27 October • Scenario 5: Metabolic modeling (Introduction)
40 20 60 0 AAAR!! 60 ft/sec * 60 sec = 3600 ft ???
40 20 60 0 AAAR!! 60 ft/sec * 60 sec = 3600 ft ???
New position 40 20 60 0 AAAR!! speed * 0.1 sec = small change in position + original position
New position 40 20 60 0 AAAR!! speed * 0.1 sec = small change in position + original position

40 20 60 0 AAAR!! x0 Position (x) Modeling: The Work Cycle • Initialize concentrations for each metabolite
40 20 60 0 AAAR!! x0 Position (x) [G6P] VMax[G6P] + Km d[F6P] / dt = dP / dt = Modeling: The Work Cycle • Initialize concentrations for each metabolite 2. Initialize constants for each reaction
40 20 60 0 AAAR!! x0 Position (x) Modeling: The Work Cycle • Initialize concentrations for each metabolite 2. Initialize constants for each reaction 3. Calculate the rate of change of each metabolite, given the current concentrations dx/dt
40 20 60 0 AAAR!! x0 Position (x) . dt = x Modeling: The Work Cycle • Initialize concentrations for each metabolite 2. Initialize constants for each reaction 3. Calculate the rate of change of each metabolite, given the current concentrations 4. Multiply each rate of change by a time increment, giving an increment for each metabolite dx/dt
