Final answer:
The complex involved in making a fatty acid is C) Fatty Acid Synthase Complex, which contains all necessary catalytic activities to synthesize fatty acids in the cytoplasm of eukaryotic cells.
Step-by-step explanation:
The complex involved in the process of making a fatty acid is the Fatty Acid Synthase Complex. This enzyme complex is responsible for the synthesis of fatty acids through a series of reactions. In eukaryotes, including humans, fatty acid synthesis occurs in the cytoplasm on the fatty acid synthase complex, which is a large, multifunctional protein complex composed of different catalytic activities necessary for building the fatty acid molecule. The activities include transacylation, reduction, dehydration, and desaturation stages, facilitating the elongation of the fatty acid chain.
Synthesis begins typically with the binding and modification of acetyl-CoA and malonyl-CoA molecules, characteristically adding two-carbon units to the growing fatty acid chain. This process is repeated until palmitoyl-CoA is eventually formed.
Consequently, the correct answer to the question is C) Fatty Acid Synthase Complex.
