Cellular Bioenergetics and Metabolic Flux
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.
For the part of you with thirty open tabs that never became anything.
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
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Cellular Bioenergetics and Metabolic Flux the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
