Identify the location of each step in gluconeogenesis.
Depending upon the origonal substrate for gluconeogeniss, pyruvate vs. lactate the number of steps vary. The pyruvate => OAA always is in the mitochondrial matrix. In the pyruvate pathway, OAA => maltate occurs in the matrix and subsiquent steps occur in the cytosol of the cell. In the lactate pathway, OAA => PEP by mitochondrial PEP carboxylkinase occurs in the mitochondrial matrix, and then PEP is transproted out of the mitochondria.
