[News] Frank Baker survives ''spontaneous combustion''

... It is of course possible to have a deficiency in catalase and over-production of acetone .. but even if the hydrogen peroxide and acetone concentrations are slight, acetone peroxide is insoluble in water and hence would be expected to accumulate.

Increase in free energy in glycolysis

... and actual Gibbs energy. The other reactions are close to equilibrium (thus they can be used by gluconeogenesis as well) and only the actual concentrations of the substrates/products determine which way it will go.

Diffusion and concentration gradient

At the atomic level, there is LOTS of space...they're just following the odds, really - if the concentrations are 5% and 70%, for every 5 particles headed one way, there's 70 headed the other.
