True about active transport are all except: (A) It is saturable, (B) It requires energy, (C) It is not a carrier mediated process, (D) It is multi-directional
Answer is D. 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.
