Figure 5.

Effective Michaelis-Menten parameters (a) K_M,S and K_M,P and (b) $V_{max}^{+}$ and $V_{max}^{-}$ as a function of volume fraction. The gray dashed lines represent the effective parameters when all concentrations are scaled to an effective volume V_eff = V(1 − ϕ) that excludes the volume occupied by inert molecules. The errors in the values calculated from uniformly resampling the GEEK parameters are smaller than 2% of the mean.
