How is malonyl-CoA formed? correct answer: Carboxylation of acetyl-CoA to form malonyl-CoA requires two steps (both use acetyl-CoA carboxylase). 1. The enzyme, complexed with biotin, acquires CO2 from HCO3 - a. Requires 1 ATP 2. The carbon is transferred to acetyl-CoA to form malonyl-CoA The overall reaction is irreversible and commits the molecule to fatty acid synthesis. Phosphate is added to HCO3 - and then removed so that biotin-carboxylase can grab the carbon. The carbon is donated to...
