A. catalysts
B. enzymes
C. carbanions
D. free radicals
Answer» B. enzymes
Explanation: Fermentation in food processing typically is the conversion of carbohydrates to alcohols and carbon dioxide or organic acids using yeasts, bacteria, or a combination there of, under anaerobic conditions. Fermentation in simple terms is the chemical conversion of sugars into ethanol. Both alcoholic fermentation and glycolysis are anaerobic fermentation processes that begin with the sugar glucose. Glycolysis requires 11 enzymes which degrade glucose to lactic acid. Alcoholic fermentation follows the same enzymatic pathway for the first 10 steps.
