Oxaloacetate can be directly converted to [PEP/glucose/citrate/malate] in the process of gluconeogenesis. Oxaloacetate can be directly converted to [PEP/glucose/citrate/ malate] upon condensation with acetyl-CoA. Oxaloacetate can be directly converted to [PEP/glucose/citrate/malate] by a reversible enzyme in the citric acid cycle. Oxaloacetate, via many enzymes, is an important source of [PEP/glucose/citrate/malate] in the liver for tissues that rely on carbohydrates for the fuel source.   help fill in the blanks
