The elongation of fatty acids is a repetition of three reactions adding carbons from ________ after each cycle until completion.

Question

Quizplus · Accepted Answer

Elongation of fatty acids occurs through the sequential addition of two carbon units, which involves a repeating cycle of three reactions with each cycle. Malonyl ACP (acyl carrier protein) is the source of the two-carbon unit that is added during each cycle of elongation. Therefore, option B (malonyl ACP) is the best choice for the missing source of carbons in elongation of fatty acids.
