Question

Which of the following criteria does not pertain to facilitated transport?

(a) Transport saturation

(b) Uphill transport

(c) Requirement of special membrane proteins

(d) High selectivity

Answer 1

Ans : (b) Uphill transport

Explanation :

Facilitated transport is the process of spontaneous passive transport or downhill transport of molecules or ions across a biological membrane via specific transmembrane integral proteins. The movement of molecules or ions is from a region of lower concentration to a region of higher concentration is uphill transport.
