ARGININE DIHYDROLASE
PATHWAY
arginine deaminase
Arginine + H2O 
citrulline
+ NH3
- ornithine carbamoyltransferase
Citrulline + inorganic orthophosphate
ornithine + carbamoyl PO
Carbamoyl PO4 + ADP
ATP
+ CO2 + NH3
Another mechanism for ATP generation is:
- phosphate acetyltransferase
*Acetyl CoA + inorganic orthophosphate acetyl
PO4 + CoA
Acetyl PO4 + ADP Acetate
+ ATP
*Acetyl CoA is produced by oxidative decarboxylation
of pyruvate.
