Fatty acid synthesis begins with a preparatory step in which acetyl CoA is transferred from mitochondria to the cytoplasm. However, it cannot pass through the membrane, so it is transported as citrate, which is cleaved to acetyl CoA and oxaloacetate. In the cytosol, acetyl CoA is converted to malonyl CoA, a three-carbon compound. Fatty acid synthesis begins with the transfer of the acetyl group from acetyl CoA to fatty acid synthase. Three-carbon groups, supplied by malonyl CoA, are added to the growing acyl chain in a series of steps involving condensation, reduction, and dehydration reactions. Elongation of the fatty acid chain stops at Two carbon atoms, after 16 cycles, as the free fatty acid is released.

Solution

Fatty acid synthesis and breakdown occur by different routes and in different parts of the cell and catalysed by different enzymes.

elongation of fatty acid chain stops at 2 carbon atoms, after 16 cycles as the free fatty acid is released.

7 co2 +7ATP+7 acetyl Co A 14 NADPH 14 H+ MALONYL Co A 7 Co2 oxidatrion palmitate malonyl ACP.

CO2 is utilized in the formation of malonyl coA and co2 produced by condensation reaction cancel each other when overall stoichiometry is calculated. the biosynthesis of fatty acid palmitate require acetyl coA andinput of chemical energy in 2 formsas the group transfer potential of ATP and reducing power of NADPH. ATP is required to attach co2 to acetyl coA to produce malonyl coA.
