Exercise 11

Assessing the energy coupling of a transport process
In this chapter we have examined coupled transport systems that rely on ATP hydrolysis, on primary gradients of Na + or H + , and on phosphotransferase systems. Suppose you have just discovered an unusual strain of bacteria that transports rhamnose across its plasma membrane. Suggest experiments that would test whether it was linked to any of these other transport systems.
