Question

The correct sequence of anaerobic reactions in yeast is
(a) Glucose Pyruvate Ethanol + Carbondioxide
(b) Glucose Pyruvate Lactic acid
(c) Glucose Pyruvate Lactic acid
(d) Glucose Pyruvate Ethanol + Carbondioxide

Answer 1

correct answer is d)

Answer 2

Dear Student,

◆ Answer -

(d) Glucose → Pyruvate → Ethanol + Carbondioxide

● Explanation -

• In yeast, glucose is converted into ethanol & CO2.
• It is an anaerobic reaction, thus dont need oxygen for reaction.
• Fermentation of glucose takes place in 2 steps (both occurring in cytoplasm of cell.) -

1. Glucose → Pyruvate ...(cytoplasm)
2. Pyruvate → Ethanol + CO2 ...(cytoplasm)

Hope this was helpful..
