Which 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.
