Question

Which of the molecule listed below is a product of fermentation of glucose by yeast?

• A. $(C_6H_{10}O_5)_n$
• B. $C_2H_5OH$
• C. $C_6H_{12}O_6$
• D. $CH_3OH$

Answer 1

Answer: (B)

$C_2H_5OH$

Answer 2

In yeast, the incomplete oxidation of glucose is achieved under anaerobic conditions by sets of reactions where pyruvic acid is converted to $CO_2$ and $C_2H_5OH$ (ethanol).
