- Which feature is typical of primary active transport? The transport protein must cross to the correct side of the membrane before the solute can bind to it. The transport protein is irreversibly phosphorylated as transport takes place. The transport protein catalyzes the conversion of ADP to ATP. The solute moves against the concentration gradient. A concentration gradient provides the energy to move substances against their concentration gradient.arrow_forwardFor primary and secondary active transport, describe the mechanism by which movement occurs, the energy requirements, the sources of energy, and the types of molecules moved?arrow_forwardDoes secondary active transport occur in the absence of primary active transport? yes or no and why or why not?arrow_forward
