Page. 840Primary and secondary transport In primary active transport, ATP is consumed directly by the transporting protein, e.g., the NaK-ATPase pump, or the calcium-dependent ATPase of the sarcoplasmic reticulum.  Secondary active transport depends indirectly on ATP as a source of energy, as in the co-transport of Na-glucose in the proximal tubule. This process depends on ATP utilized by the NaK-ATPase pump.  Glucose moves up a concentration gradient via secondary active transport.
