Which Statement Applies to Synthesis of Fatty Acids in E

Question

Which statement applies to synthesis of fatty acids in E. coli extracts? A) Acyl intermediates are thioesters of a low molecular weight protein called acyl carrier protein. B) CO2or HCO3^- is essential. C) Reducing equivalents are provided by NADPH. D) The ultimate source of all the carbon atoms in the fatty acid product is acetyl-CoA. E) All of the statements apply to synthesis of fatty acids in E. coli extracts.

Accepted Answer

All of the statements apply to the synthesis of fatty acids in E. coli extracts. The synthesis of fatty acids involves acyl intermediates that are thioesters of the low molecular weight protein called acyl carrier protein. The essential enzymes for fatty acid synthesis, such as CO₂ or HCO₃^-, are present in E. coli extracts. Reducing equivalents in the form of NADPH are necessary for fatty acid synthesis, and the ultimate source for all the carbon atoms in the fatty acid product is acetyl-CoA.
