Understanding Acetyl-CoA Carboxylase (ACC)

Acetyl-CoA Carboxylase (ACC)

The assembly of the Acetyl-CoA carboxylase or the ACC to form long filaments increases the activity. The correct option is option D.

Acetyl-CoA carboxylase, or the ACC, is basically a biotin-dependent enzyme which catalyzes the irreversible carboxylation of the acetyl-CoA in order to produce the malonyl-CoA via two catalytic activities which are the biotin carboxylase, represented as BC and the carboxyltransferase or the CT.

ACC is basically a multi-subunit enzyme which is present in most prokaryotes as well as in the chloroplasts of most of the plants as well as algae, whereas it exists a large and multi-domain enzyme in the cytoplasm of a number of eukaryotes.
