Question

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

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

Answer 1

The correct option is A $M{g}^{++}$

During anaerobic respiration, the conversion of pyruvate into acetaldehyde, along with co-enzyme TPP, the co-factor required is $M{g}^{2+}$. $M{g}^{2+}$ is the cofactor required by both Pyruvate decarboxylase and pyruvate dehydrogenase.
