ii) Symport Transport

Co-transport Mechanism :-
ii) Symport : Symport is define as the transportation type active transport in which transportation of nutritional is same two elements/gradients molecules passes membrane by simultaneously enters in the cell environment known as "#Symport" Transport Mechanism such two subtances are linked transport in the same direction from exterior to interior of cell membrane ...

Example : Lactose Permease of E.coli transports a lactose molecule inside the cell membrane and Simultaneously Proton Gradient enters in thr cell.

This is combined and are also in same direction but here two things are getting transports at a time or same time...

Here you can see the arrows of Symport Mechanism 

Molecule A & B are in same direction and pasaing together from the Membrane of cell...even having same time same directions.
