Figure 2.

Dynamics of the cell layer in experiment (A and C) and simulation (B and D). (A) The time-space plot is constructed along the horizontal line in Fig. 1C. (C) Time-space plot of the measured NADH-fluorescence in nonoscillating yeast cell layers. (Inset) NADH-fluorescence in a stirred cell solution. (B and D) Simulated time-space plots corresponding to panels A and C. Shown are variables X_i in a part of the two-dimensional array. Parameters: J^max = 8 × 10⁻³, K_M = 3, α^main = 3 × 10⁻⁴, n = 2, κ = 0.13, ϕ = 0.1, d_X = 0.05, d_Y = 0.002; (B) k₂ = 0.15, and (D) k₂ = 0.05. Substrate is applied to the system via an initial extracellular substrate concentration at two compartments each with X^ex(t₀) = 187,210.
