← ScienceWhich rate-limiting effect accelerates ethanol production in fermentation vessels using immobilized enzymatic catalysts, once ethanol concentration exceeds ten percent?
A)Product inhibition by ethanol✓
B)Enzyme denaturation by substrate
C)Substrate depletion near catalyst
D)Temperature variance within the reactor
💡 Explanation
Product inhibition reduces the availability of active sites, therefore ethanol production slows because the increased concentration allows more ethanol to bind to the enzyme, rather than the substrate.
