The following corrections are noted:

1. Page 3318, under “Cell size and composition”, on line 5, “radius = 10 μm” should be “radius = 11 μm”.

2. Page 3319, under “Isoproterenol/β₁ adrenergic receptor/G_s module”, the third equation “L_IsoR_β1G_s = (L_Iso × R_β1free × G_sfree)/(K_H/K_L × K_C)” should be “L_IsoR_β1G_s = (L_Iso × R_β1free × G_sfree)/(K_H × K_C)”.

3. Page 3319, under “Acetylcholine/M₂ muscarinic receptor/G_i module”, the third equation “L_AchR_M2G_i = (L_Ach × R_M2free × G_ifree)/(K_H/K_L × K_C)” should be “L_AchR_M2G_i = (L_Ach × R_M2free × G_ifree)/(K_H × K_C)”.

4. Page 3327, under “Table 4 G-protein activation module”, in row 5, “activation rate constant for LRG_i complexes” should be “activation rate constant for RG_i complexes”; in row 6, “activation rate constant for RG_i complexes” should be “activation rate constant for LRG_i complexes”; in row 7, “activation rate constant for LRG_s complexes” should be “activation rate constant for RG_s complexes”; and in row 8, “activation rate constant for RG_s complexes” should be “activation rate constant for LRG_s complexes”.

5. Page 3327, under “Table 6 Adenylyl cyclase 4/7”, in row 2, “0.379 × 10⁻³” should be “0.136”.

All equations were implemented correctly in the numerical calculations.
