Which statement is true concerning primary active transport versus secondary active transport?
Primary uses an electrochemical gradient to drive transport across a membrane
Primary uses ATP for energy to pump molecules from low to high concentration

Primary uses ATP for energy to pump molecules from low to high concentration

Diffusion across the membrane depends upon:
the size of the molecule
