Which of the following criteria does not pertain to fecilitated transport?
Options
(a) High selectively
(b) Transport saturation
(c) Uphill transport
(d) Requirement of special membrane proteins
Correct Answer:
Uphill transport
Explanation:
Substances that have a hydrophilic moeity, find it difficult to pass through the membrane, their movement has to be faciilitated by the membrane protein without expenditure of ATP energy. Facilitated diffusion cannot caue net transport of molecules from a low to high concentration or uphill transport. Transport rate reaches a maximum when all of teh protein transporters are being used (saturation). Facilitated diffusion is very specific.
