Question

During anaerobic respiration the conversion of pyruvate into acetaldehyde, along with co-enzyme TPP, the cofactor required is

• A. $M{g}^{++}$.
• B. $M{n}^{++}$.
• C. $F{e}^{++}$.
• D. $Z{n}^{++}$.

Answer 1

Answer: (D)

$Z{n}^{++}$.

When Pyruvate undergoes decarboxylation by removal of carbon dioxide to form Acetaldehyde co enzyme TPP and cofactor Zn is required. Thus the correct answer is option D.
