One reaction in this pathway requires the use of phosphoenolpyruvate carboxykinase in the GTP-dependent formation of PEP.
Muscle and brain cells cannot carry out this pathway because they lack an enzyme found on the luminal side of the endoplasmic reticulum in certain other cells. One step in this pathway involves the conversion of an intermediate into fumarate, aspartate, or malate in order to transport it into the cytosol. This pathway uses enzymes in the FBPase family to make energetically favorable the reverse of a reaction that uses PFK. One reaction in this pathway requires the use of phosphoenolpyruvate carboxykinase in the GTP-dependent formation of PEP. The previous step requires the coenzyme biotin and forms oxaloacetate from pyruvate. For 10 points, name this pathway carried out in the liver, which converts non-carbohydrate compounds into new glucose.
