<Ul> <Li> This picture represents symport . The yellow triangle shows the concentration gradient for the yellow circles while the green triangle shows the concentration gradient for the green circles and the purple rods are the transport protein bundle . The green circles are moving against their concentration gradient through a transport protein which requires energy while the yellow circles move down their concentration gradient which releases energy . The yellow circles produce more energy through chemiosmosis than what is required to move the green circles so the movement is coupled and some energy is cancelled out . One example is the lactose permease which allows protons to go down its concentration gradient into the cell while also pumping lactose into the cell .

The yellow triangle shows the concentration gradient for the yellow circles and the purple rods are the transport protein bundle . Since they move down their concentration gradient through a transport protein, they can release energy as a result of chemiosmosis .
