Primary and secondary transport
In primary active transport, ATP is consumed directly by the transporting protein, (e.g., the Na/K-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 Na/K-ATPase pump.
Glucose moves up a concentration gradient via secondary active transport.
