All of the following transpo processes follow 'saturation kinetics' except:
Simple diffusion occurs by viue of kinetic energy of the paicles. Thus, it will never stop, except at absolute zero temperature; neither will it show any saturation kinetics. Saturation kinetics are exhibited by those transpos which are mediated by carriers. Carriers have finite number of binding sites, to bind and transpo a substance. When all the binding sites are occupied, the carrier is said to be "saturated". Options A, B, and D are carrier mediated transpos.
