Which outcome limits methane production when biogas digester feedstock lacks trace elements?

💡 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.
