Palmitic acid and acetyl $CoA$

Vedclass · Answer

(B) The energy content of a molecule is determined by the amount of $ATP$ produced upon its complete oxidation. $1$. Palmitic acid is a fatty acid with a long carbon chain $(C_{16}H_{32}O_2)$. Upon complete oxidation, one mole of palmitic acid yields approximately $129$ $ATP$ molecules. $2$. Acetyl $CoA$ is a two-carbon compound. Upon complete oxidation in the $TCA$ cycle, one mole of acetyl $CoA$ yields $12$ $ATP$ molecules. Therefore, palmitic acid represents the highest energy molecule, and acetyl $CoA$ represents the lowest energy molecule among the given options. Thus, the correct pair is $Palmitic 	ext{ acid and acetyl } CoA$.

Which of the following pairs is a combination of the highest and lowest energy molecules?
