Question

In the presence of TPP and carboxylase enzyme, pyruvic acid is converted into

• A. Citric acid and $C{O}_2$
• B. Acetaldehyde and $C{O}_2$
• C. Ethyl alcohol and $C{O}_2$
• D. Acetic acid and $C{O}_2$

Answer 1

Answer: (B)

Acetaldehyde and $C{O}_2$

In alcoholic fermentation, pyruvic acid is converted into acetaldehyde and CO${}_2$ in the presence of TPP and carboxylase. Acetaldehyde is further oxidised to form ethanol.

So, the correct answer is 'Acetaldehyde and CO${}_2$'.
