WebPlants and bacteria can convert acetyl-CoA to glucose via the glyoxylate cycle. It is a modified version of the TCA cycle; an extra malate is produced which can be converted to glucose. Since animals lack this cycle, they cannot use acetyl-CoA to make glucose because it would stop the TCA cycle.
