  1. Which of the following is essential for conversion of pyruvic acid into acetyl Co-A?
    1. LAA
    2. NAD
    3. TPP
    4. All of these
Correct Option: D

During aerobic oxidation of pyruvic acid, first of all there is activation of pyruvic acid in which NAD and coenzyme react with pyruvic acid and oxidative decarboxylation takes place leading to the formation of acetyl Co-A. In this process, lipoic acid amide (LAA), thyamine pyrophosphate (TPP) and NAD are essential to perform this reaction.
