Cellular Bioenergetics and Metabolic Flux
A master-level exploration of the molecular machinery, thermodynamic constraints, and regulatory networks that govern how cells extract and transform energy.
Like Duolingo, but for Cellular Bioenergetics and Metabolic Flux. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
87 levels across 8 sections, about 174 minutes end to end, roughly 35 days at five minutes a day. It moves through Metabolic Control and Thermodynamics, Glycolysis: Beyond the Canonical Pathway, The Mitochondrial Gateway, The TCA Cycle as a Metabolic Hub, The Electron Transport Chain (ETC), Chemiosmosis and the ATP Motor, Metabolic Integration and Signaling, and Bioenergetics in Pathology.

Key ideas in Cellular Bioenergetics and Metabolic Flux
- Equilibrium represents a state of maximum entropy where ΔG is zero
- Cellular respiration maintains a high [ATP]/[ADP] ratio far above equilibrium
- A steady state requires constant energy input
- Thermodynamics of steady states
- ΔG = ΔG°' + RT ln(Q)
- The cell maintains very low product concentrations
- Standard conditions vs reality
- Calculating actual free energy
- Flux is determined by the degree of displacement from equilibrium
- High reactant concentration only increases flux if it is not countered by a high product concentration
- Equilibrium represents biological death
- The 'force' of respiration is the steepness of the chemical potential gradient
- Regulatory enzymes like Hexokinase operate far from equilibrium to act as one-way valves
- Calculating actual free energy change
- Near-equilibrium reactions allow the pathway to respond instantly to changes
- Total flux is controlled at bottleneck steps with largest ΔG displacement
