Vedclass · Answer

(B) Pyruvic acid $(CH_3COCOOH)$ is a $3$-carbon compound produced at the end of glycolysis.During aerobic respiration,pyruvic acid undergoes oxidative decarboxylation to form Acetyl-CoA,releasing one molecule of $CO_2$.Subsequently,the Acetyl-CoA enters the Krebs cycle (Tricarboxylic Acid Cycle),where it is completely oxidized to release two more molecules of $CO_2$.Therefore,the total number of $CO_2$ molecules released during the complete oxidation of one molecule of pyruvic acid is $1 + 2 = 3$.

How many molecules of $CO_2$ are released during the complete oxidation of one molecule of pyruvic acid?
