Three main ways of active transport 光能 电化学梯度 脂双层 ATP ADP+Pi ATP驱动泵 协同转运蛋白 光驱动泵 1.Couple uphill transport to the hydrolysis of ATP. 2.Couple the uphill transport of one solute across membrane to the downhill transport of another. 3.Mainly in bacteria,couple uphill transport to an input of energy from light.
