<prompt> True about active transport are all exceptIt is saturableIt requires energyIt is not a carrier mediated processIt is multi-directional  <response>: Ans: d It is multi-directional Ref: Vasudevan 4th ed p. 16Active transport is not multi-directional. It is unidirectional.Active transport: -It requires energy.It is unidirectional.-It requires specialised proteins called Transporters.It is saturable.These transporters are susceptible to inhibition.Note:Facilitated diffusion is carrier mediated.
