The enzyme that converts glucose to ethyl alcohol is

  • A.Maltase
  • B.Zymase
  • C.Diastase
  • D.Invertase

Answer: B

Zymase converts glucose to ethyl alcohol.

Secreted by yeast, it catalyses \[\mathrm{C_6H_{12}O_6 \rightarrow 2\,C_2H_5OH + 2\,CO_2}\] Invertase first splits sucrose into glucose and fructose, diastase converts starch to maltose, and maltase maltose to glucose - zymase completes the chain.
