Which consequence results when temperature limits the substrate diffusion rate in enzymatic biofuel cell?

A)Reduced maximum achievable current density
B)Increased activation energy requirement
C)Enhanced electron transport chain efficiency
D)Suppressed anode biofilm formation

💡 Explanation

Reduced substrate diffusion, due to low temperature, limits the reactants reaching the enzyme; thus, limiting the enzymatic reaction rate reduces the maximum current usable because the Enzyme kinetics are constrained rather than some electronic effect, therefore changing overall performance rating.
