A. Write a series of balanced equations, and fill in the blanks for an overall equation, for the complete oxidation of 2 mol of glutamate to 2 mol of α-ketoglutarate and 1 mol of urea. Note that the overall equation (net reaction) does not include aspartate, fumarate, or oxaloacetate, so you must include balanced equations for the interconversion of these molecules. (Hint: what pathway converts fumarate to oxaloacetate?) For reference, the urea cycle figure is shown on the back. You will need a total of 9 to 11 reactions in order to generate the balanced overall equation. Overall equation/net reaction (fill in stoichiometry):(The stoichiometry of water and H+is not important here, so don’t stress about that)2 glutamate + __CO2+ 4 H2O + __NAD++ __ATP →2 α-ketoglutarate + urea + ___NADH + 7 H++ __ADP + __AMP + __Pi+ __PPi

b. Based on the final equation above, does the process result in a net gain or loss of ATP equivalents? How many?
