Definition For Active Transport

Root hair cells pull minerals from the soil even when those minerals are scarce.

: Uses the energy already stored in an electrochemical gradient (created by primary transport) to move a different molecule. It can be a symport (both moving same direction) or antiport (opposite directions). definition for active transport

In this version, the cell doesn't use ATP directly for the transport. Instead, it uses the energy from an electrochemical gradient created by primary active transport. Two molecules move in the same direction. Antiport: Two molecules move in opposite directions. 3. Bulk Transport Root hair cells pull minerals from the soil
