← ScienceWhich outcome limits methane production when biogas digester feedstock lacks trace elements?
A)Methanogen enzyme active site inactivity✓
B)Increased hydrogen sulfide byproduct production
C)Substrate accumulation inhibiting hydrolysis
D)Elevated digester pH disrupting archaea
💡 Explanation
Inactive metaloenzymes cause reduced methane production because the trace nutrient deficiency prevents proper folding or function of the enzyme's active site responsible for catalysing the methanation reaction; therefore methanogens cannot complete metabolic pathways, rather than producing other byproducts.
