WebCitrate, a Krebs cycle (i.e., TCA cycle or citric acid cycle) intermediate, is generated by many bacteria; however, utilization of exogenous citrate requires the presence of citrate transport proteins (permeases) (7). Upon uptake by the cell, citrate is cleaved by citrate lyase to oxaloacetate and acetate. The oxaloacetate is then metabolized to WebProcedure Reaction of sodium hydroxide solution and dilute hydrochloric acid Stand the polystyrene cup in the beaker.
