Substrate to outcome
Start with the input, destination, key transformation and biological outcome. A pathway becomes easier when its purpose is visible.
FLOW · REGULATION · INTEGRATION
Follow the pathway.
Find the control.
Use this pack to organise biochemical mechanisms before adding source-specific structures, enzymes and values from lawful resources.
Find the control point
Ask which step commits the pathway, what signal changes it and why the cell would favour one direction in that context.
Track the cost and gain
Connect energy demand, carrier molecules and cellular location. Do not memorise a reaction without its energetic role.
Context selects the pathway
Fed state, fasting, tissue, activity and stress change which mechanisms dominate. State the context before applying the model.
TEST THE PATHWAY
Recall purpose before steps.
Use the original check, then add detailed enzymes and structures from sources you lawfully access.
