Mos ttransport processes require input of energy - either in the form of ATPor membrane potential. When ATP is the source of energy, transport also requires the function of a dedicated ATPase. The molecular mechanisms of transport ATPases are poorly understood. It is not known how the energy is transduced to carry out transport, or what determines the polarity of transport. An intriguing question also concerns the substrate specificty of the transport proteins.
Most transporters are able to carry out transport of only one or a set of related substrates.
