In Comparing Fatty Acid Biosynthesis With Oxidation of Fatty Acids,which of the Following Statements Is Incorrect
Multiple Choice
In comparing fatty acid biosynthesis with oxidation of fatty acids,which of the following statements is incorrect?
A) A thioester derivative of crotonic acid (trans-2-butenoic acid) is an intermediate in the synthetic path,but not in the degradative path.
B) A thioester derivative of D- -hydroxybutyrate is an intermediate in the synthetic path,not in the degradative path.
C) Fatty acid biosynthesis uses NADPH exclusively,whereas oxidation uses NAD+ exclusively.
D) Fatty acid degradation is catalyzed by cytosolic enzymes;fatty acid synthesis by mitochondrial enzymes.
E) The condensation of two moles of acetyl-CoA in the presence of a crude extract is more rapid in bicarbonate buffer than in phosphate buffer at the same pH;the cleavage of acetoacetyl-CoA proceeds equally well in either buffer.
